-cdrskin was the initiator of the whitelist functionality within libburn.
-Now it has problems to obviously comply with the new API best practice
-presciptions literally. Therefore this explanation:
-
-On start it restricts the library to a single drive if it already knows the
-persistent address by option dev= . This is done with a combination of
-burn_drive_add_whitelist() and burn_drive_scan(). Not compliant to the
-literal strong urge but in fact exactly fulfilling the reason for that
-urge in the API: any scanned drive might be opened exclusively after
-burn_drive_scan(). It is kernel dependent wether this behavior is on, off
-or switchable. The sysdamin will want it on - but only for one drive.
-
-So with dev=... cdrskin complies to the spirit of the strong urge.
-Without dev=... it has to leave out the whitelist in order to enable bus
-scanning and implicit drive address 0. A tradition of 9 months shall not
-be broken. So burns without dev= will stay possible - but harmless only
-on single drive systems.
-
-Burns without dev= resp. with dev=number are harmless on multi-drive systems.
-
-This is because Cdrskin_grab_drive() either drops the unwanted drives or
-it enforces a restart of the library with the desired drive's persistent
-address. This restart then really uses the strongly urged function
-burn_drive_scan_and_grab().
-Thus, cdrskin complies with the new spirit of API by closing down libburn
-or by dropping unused drives as soon as the persistent drive address is
-known and the drive is to be used with a long running operation. To my
-knowlege all long running operations in cdrskin need a grabbed drive.
-
-This spaghetti approach seems necessary to keep small the impact of new API
-urge on cdrskin's stability. cdrskin suffers from having donated the body
-parts which have been transplanted to libburn in order to create
- burn_drive_scan_and_grab() . The desired sysadmin friendlyness was already
-achieved by most cdrskin runs. The remaining problem situations should now
-be defused by releasing any short time grabbed flocks of drives during the

 How to handle finalizing ?
 
-Check wether current_profile is kept up to date with each possible media change
-
-Make drive_info reflect DVD capabilities
-Make proper use of reflected capabilities (e.g. in burn_drive_inquire_media())
-
 Rectify mmc_read_atip speed interpretation. 12x media are reported as 10x. I never heard of 6x media.

+with CD media, but retrieves additional information from the existing ISO
+image and finally manipulates the start sectors of this existing image.
+So for growable ISO filesystems on DVD-RAM or DVD+RW growisofs is the only
+choice, currently.
+
+
+cdrskin can offer DVD multi-session only with sequential DVD-R[W]. Associated
+options blank=, -multi, -msinfo and -toc are available in this case. Thus
+sequential DVD-RW behave much like large CD-RW with possibly more than 99
 tracks.
 
-To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
-they would write to a traditional tape device. Try old tape archiver
-commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
-I have heard rumors that DVD-RW in mode "restricted overwrite" would be
-block device ready, too. My burner is not a real friend of DVD-RW and
-in an experiment the burn worked fine - but the result was not identical
-to the stream sent to the device. I had similar failure with DVD-RAM, too.
-
-Beware of the impact of a slow block device on overall system i/o buffering.
-It is wise to curb its input to a speed which it is able to deliver to media.
-Else your i/o dedicated RAM might buffer a big amount of stream data.

+
+
+-------------------------------------------------------------------------------
+About blank, appendable and finalized CD media :
+
+CD media have to be blank or appendable in order to be writeable in TAO mode.
+The according status may be inquired by 51h READ DISC INFORMATION requesting
+Data Type 000b Standard Disc Information, where reply value Disc Status
+indicates:
+ 00b   blank
+ 01b   appendable
+ 10b   finalized
+ 11b   others (unsuitable for this recipe)
+(mmc5r03c.pdf 6.22.3.1.4)
+
+CD-RW which are finalized or appendable may be blanked by command A1h BLANK
+with blanking types 000b "Blank the disc" or 001b "Minimally blank the disc".
+The Start Address/Track Number will be ignored so it may well be 0.
+
+Because the operation is long running it is advised to set the Immed bit and to
+watch the progress by commands 00h TEST UNIT READY and 03h REQUEST SENSE
+with DESC bit set to 0 for fixed format reply.
+It is done when 00h succeeds and 03h reports 0 in PROGRESS INDICATION

+
+
+-------------------------------------------------------------------------------
+Writing a session to CD in TAO mode :
+
+The writing method for blank or appendable media is the same. A new session
+will get created automatically by the first track when it is written. If the
+media is blank then the new session will be the first and only one in the
+table of content. If the media is appendable then a new session will be
+appended to the existing sessions. In any case the new track will be the
+first one in the new session.
+
+Speed may be set by BBh SET CD SPEED parameter Drive Write Speed. Note that
+kbytes/sec means 1000 bytes/sec and not 1024/sec. Rotational control should
+be set to 00b. 1x CD speed is 176.4 kbytes/sec. Speed is usually set to the
+next lower possible value by the drive. So it is helpful to add a few 
+kbytes/sec just in case the drive has rounding problems.
+(mmc5r03c.pdf 6.37)
+
+Before writing can occur, a Write Parameters mode page 05h has to be composed
+and transmitted via 55h MODE SELECT. Mode page 05h describes several burn
+parameters:
+ BUFE             Buffer Underrun protection      0=off, 1=on
+ Test Write       -dummy mode for writing         0=off, 1=on

+
+

+Number set to FFh. The Next Writeable Address as of table 500 is the number
+to start writing with.
+(mmc5r03c.pdf 6.27 )
+
+Writing is performed by one or more 2Ah WRITE transactions with the Logical
+Block Address counted up from the initial number in sync with the number of
+blocks written. I.e the Transfer Length of the previous 2Ah WRITE has to be
+added to the Logical Block Address for the next 2Ah WRITE. Only full blocks
+can be written.
+(mmc5r03c.pdf, 6.44)

+Older MMC specifies a valid Logical Track Number FFh to depict the open track.
+MMC-5 is quite silent about this. FFh works for my drives.
+(mmc5r03c.pdf 6.3.3.1.2)
+
+After that, a new track may be written beginning with sending the mode page 05h
+again. It is not tested wether 05h can be omitted if Track Mode and Data Block
+Type are the same as with the previous track.
+The new track will be added to the session which was opened by the first track.
+
+After the last track of a session, 5Bh CLOSE TRACK SESSION Close Function 010b
+with Logical Track Number 0 closes the session. It depends on the Multi-Session
+value in mode page 05h wether the disc is finalized or stays appendable.

+-------------------------------------------------------------------------------
+Obtaining CD multi-session info for extending ISO-9660 filesystems :
+
+Program mkisofs expects two numbers with its option -C which describe the
+situation on an appendable CD which already contains a ISO-9660 filesystem
+in the first track of the last session.
+
+The first number is the Logical Block Address of that track containing the
+existing ISO-9660 filesystem image. This number is needed for mkisofs option
+-M to connect to the existing image. The new image will refer to files in
+the previously existing image. mkisofs option -M needs read access to the
+CD or a blockwise copy of it on hard disk. 
+The number is gained by 43h READ TOC/PMA/ATIP.
+(mmc5r03c.pdf 6.26)
+Untested is Format 0001b which in table 478 promises quick access via
+Start Address Of First Track In Last Session.
+(mmc5r03c.pdf 6.26.2.5 table 478, 6.26.3.3.1)
+libburn gets the number from its Table Of Content model which is obtained
+by 43h READ TOC/PMA/ATIP, Format 0010b. See below.
+
+The second number is an exact prediction of the Logical Block Address of the
+new track which will contain the newly generated ISO-9660 image.
+Even without mkisofs option -M this second number is still needed to make the
+inner block address pointers of the image match the Logical Block Addresses
+on CD. For that one may inquire 52h READ TRACK INFORMATION with
+Address/Number Type set to 01b and Logical Block Address/Track/Session
+Number set to FFh. The Next Writeable Address as of table 500 is the number
+to use.
+(mmc5r03c.pdf 6.27 )
+
+
+-------------------------------------------------------------------------------
+Obtaining a Table Of Content from CD :
+
+The structure of a CD is comprised of sessions. Each session contains one or
+more tracks and is followed by a lead-out. A track has an address and a length.
+
+Table of content information is gained by 43h READ TOC/PMA/ATIP, Format 0010b.
+(mmc5r03c.pdf 6.26.2.5 table 478)
+
+The number of sessions is given by Last Complete Session Number.
+The number of TOC Track descriptors is: (TOC Data Length - 2)/11 . 
+
+Each TOC Track Descriptor contains a Session Number.
+
+If POINT is >= 1 and <= 99 (63h) then the descriptor is about the track of
+which POINT tells the number.
+The start address of this track can be read from PMIN, PSEC, PFRAME where
+it is encoded in MSF format:
+blocks = frames - 150, 75 frames = 1 sec , 60 sec = 1 min.
+The length of the track is given by MIN,SEC,FRAME in the same format.
+
+If POINT = A0h then the descriptor tells in PMIN the first track number of its
+session.
+POINT = A1h tells in PMIN the last track number of its session.
+POINT = A2h describes in PMIN, PSEC, PFRAME the lead-out of a session, i.e the
+first address after the session's end. (Next writeable address typically is
+lead-out + 11400 after the first session, lead-out + 6900 after further
+sessions.)
+POINT = B0h tells in MIN,SEC,FRAME this next writeable address or FFh,FFh,FFh
+for finalized disc.
+(mmc5r03c.pdf 6.26.3.4 table 489, 4.2.3.7 Mode-1 Q, Mode-5 Q)
+
+
+In libburn the address of the first track in the last session is obtained from
+the last session's POINT = A0h and from the track descriptor with the POINT
+value matching the PMIN value of the A0h descriptor.
+Untested is wether POINT = B0h and 52h READ TRACK INFORMATION are always in
+sync. libburn uses the info provided by 52h READ TRACK INFORMATION.

+Recognition of media type and state (blank, appendable, finalized) is as
+described in the TAO Multi-Session CD Cookbook. See there.
+
+The MMC specs do not give much hint about the combination of SAO and
+multi-session. My drives refused not only on a few experiments which i did
+in libburn but also failed with cdrecord -sao on an appendable CD.
+So for now only blank CD seem to be suitable for SAO writing.  
+
+Different from TAO mode, the whole session layout is announced to the drive by
+sending a Cue Sheet. This implies that the sizes of the tracks have to be known
+in advance, which is a heavy drawback when dealing with track data sources like
+stdin, named pipes or sockets.
+Nevertheless, SAO seems to be best writing mode for audio purposes, as our
+audio expert Lorenzo Taylor found out.
+
+A SAO session in libburn may either consist entirely of audio tracks or
+entirely of data tracks. For mixed sessions, only TAO is usable yet.
+

+
+
+-------------------------------------------------------------------------------
+Composing a Cue Sheet (either audio or data, but not mixed) :
+
+The Cue Sheet will get submitted to the drive by 5Dh SEND CUE SHEET.
+Each entry of the sheet is of 8 bytes size. Its fields are named
+CTL|ADR, TNO, INDEX, DATA FORM, SCMS, MIN, SEC, FRAME .
+(mmc5r03c.pdf 6.33)
+
+CTL is 40h for data and 00h for audio.
+(mmc5r03c.pdf 6.33.3.4)
+ADR is always 01h.
+TNO is the track number (1 to 99).
+INDEX is a subaddress within tracks. This recipe uses only INDEX 01h within
+tracks.
+(mmc5r03c.pdf 4.2.3.5.2)
+DATA FORM is 00h for audio payload , 10h for data. (01h for audio pause is not
+used in libburn). 
+(mmc5r03c.pdf 6.33.3.11 CD-DA Data Form, 6.33.3.12 CD-ROM mode 1 Form)
+SCMS is always 00h.
+MIN, SEC, FRAME give the MSF address where the described data entity starts.
+LBA = frames - 150, 75 frames = 1 sec , 60 sec = 1 min.
+This address must increase from entry to entry (or at least stay equal).
+
+
+The first entry describes the Lead-in. Its content is 
+(CTL|ADR ,00h,00h,01h,00h,00h,00h,00h)
+With the CTL|ADR for the first track: 41h for data, 01h for audio.
+
+The LBA for the first write is negative: -150. This corresponds to MSF address
+00h:00h:00h. All addresses are to be given in MSF format.
+The first information track on disc is preceded by a pause encoding of 2 sec:
+(CTL|ADR,01h,00h, DATA FORM ,00h,00h,00h,00h) 
+with DATA FORM = 00h for audio and 10h for data. By those 2 seconds the MSF
+address increases to 00h:02h:00h = LBA 0.
+
+Each track is represented by an entry
+(CTL|ADR, TNO ,01h,DATA FORM,00h, MIN , SEC , FRAME)
+TNO gives the track number. MIN, SEC, FRAME give the MSF address which becomes
+the start address of the track. The MSF address is then increased by the size
+of the track (to be used with next track or with lead-out).
+
+A track must at least contain 300 payload blocks: 4 seconds of audio or
+600 KiB of data.
+(mmc5r03c.pdf 6.33.3.6)
+
+At the end of the session there is a lead-out entry
+(CTL|ADR,AAh,01h,01h,00h,MIN,SEC,FRAME)
+marking the end of the last track. (With libburn CTL is as of the last track.)

+kbytes/sec means 1000 bytes/sec and not 1024/sec. Rotational control should
+be set to 00b. 1x CD speed is 176.4 kbytes/sec. Speed is usually set to the
+next lower possible value by the drive. So it is helpful to add a few
+kbytes/sec just in case the drive has rounding problems.

+55h MODE SELECT. This page describes the following parameters:
+ BUFE             Buffer Underrun protection      0=off, 1=on
+ Test Write       -dummy mode for writing         0=off, 1=on

+                                                  11b = keep appendable

+Any other parameters may be set to 0.
+Mode page data as of MMC-5 table 644 are preceded by a Mode Parameter Header
+as of SPC-3 table 240. This 8-byte header may be filled with zeros.

+(spc3r23.pdf 6.8 MODE SELECT, 7.4.3 Mode parameter header formats)
+
+The Cue Sheet is submitted to the drive by 5Dh SEND CUE SHEET. Cue Sheet Size
+is 8 times the number of entries.
+(mmc5r03c.pdf 6.33)
+
+Writing is performed by multiple 2Ah WRITE transactions with the Logical
+Block Address counted up from the initial number in sync with the number of
+blocks written. I.e the Transfer Length of the previous 2Ah WRITE has to be
+added to the Logical Block Address for the next 2Ah WRITE. Only full blocks
+can be written.
+(mmc5r03c.pdf, 6.44)
+Writing begins at LBA -150 which is to be transmitted as 4-byte, Big-endian,
+two's-complement. E.g:  -150 = FFh FFh FFh 6Ah. This is the natural form found
+with about any 32-bit processor, so only the endianness has to be taken into
+respect when converting a 32-bit integer into a LBA for command 2Ah WRITE.
+
+
+At first the mandatory pause preceding the first track has to be written as
+150 blocks of the matching sector size: 2048 for data, 2352 for audio.
+By this, the LBA increases from -150 to 0.
+
+Next the tracks' payload is sent. For each track exactly the number of blocks
+has to be transmitted as is announced in the Cue Sheet by the difference
+of the track's own start address and the start address of the next entry in
+the Cue Sheet. After each write the LBA for the next write has to be increased
+by the number of blocks transmitted. Just like with TAO writing.
+
+There is no separator between the tracks of a pure mode SAO session.
+(If the session was mixed mode, there would be extended Pre-gaps and Post-gaps
+between data mode tracks and audio mode tracks.)
+(libburn sends its own buffer to the drive at the end of each track but does
+not sync the drive's chache. It is unclear wether this separation of tracks
+on the level of 2Ah WRITE is necessary with a pure mode session. It does not
+harm in any case and would probably be unavoidable if audio and data tracks
+were mixed.)
+
+When writing of all tracks is done, it is mandatory to force the drive's buffer
+to media by 35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+No further finalization is necessary. (I.e. no 5Bh CLOSE TRACK SESSION.)
+
+
+----------------------------------------------------------------------------
+What is known about mixed mode sessions :
+
+For now, SAO sessions with a mix of data and audio are not supported in
+libburn. Here are the reasons why.
+
+Obviously the code of http://icculus.org/burn is incomplete in this aspect.
+In mmc5r03c.pdf comparison of table 555 and 6.33.3.18 seems self-contradicting.
+(The second Pre-gap in table 555 does not match any of the criteria of
+6.33.3.18. Also, there is no Post-gap shown in table 555 although 6.33.3.19
+would prescribe some.)
+
+If a data track follows an audio track then the data track gets a preceding
+extended Pre-gap:
+(CTL|ADR, TNO ,01h,DATA FORM,00h, MIN , SEC , FRAME)
+with TNO already the number of the data track. The MSF address is to be
+increased by 3 seconds. The first second of the extended Pre-gap needs to be
+written in the audio track's mode and the other 2 seconds are to be written
+in the data track's mode.
+(libburn compares DATA FORM rather than burn_track.mode . Wrong ?)
+(libburn currently does only 2 seconds and the second part of Pre-gap. There is
+an issue with burn_track.pregap1 about this. Seems libburn mistakes the pause
+preceding track 1 for a part 2 of an extended Pre-gap.)
+
+If a data track is followed by an audio track then it gets a Post-gap of at
+least two seconds.
+No example of Post-gap is given for Cue Sheet. Maybe it is to be added to the
+track, or maybe it gets an own Cue Sheet entry ... who knows ?
+(libburn contains write code for pregap1, pregap2 and postgap. But only
+pregap2 ever gets activated. Once hackingly for the first 2 second pause, once
+incompletely for a change of DATA FORM.)
+
+Seems nobody ever tested this. Libburnia simply knows no use case where the
+correctness of Pre-gap and Post-gap would become evident.

+
+A short compilation of the write model:
+- Overwriting in general
+
+The recipes described here are depending on formatting state:
+- DVD-RAM, fully formatted DVD+RW or DVD-RW
+- Unformatted DVD+RW
+- Partly formatted DVD+RW
+- Unformatted DVD-RW
+- Partly formatted DVD-RW
+- Intermediate state DVD-RW
+
+
+-------------------------------------------------------------------------------
+Overwriting in general :
+
+Depending on media type, some kind of formatting has to have happened before
+data can be written. Formatting may happen separately from writing or
+simultaneously. See the particular recipes below.
+
+No Write Parameters mode page 05h is to be sent. Speed can be influenced by
+B6h SET STREAMING , speed capabilities can be inquired by ACh GET PERFORMANCE.
+It is advised to set only speeds and sizes which are returned by ACh.
+(mmc5r03c.pdf 6.39 SET STREAMING, 6.8 GET PERFORMANCE)
+Optimal performance is promised without any speed setting. But my experiments
+showed that SET STREAMING values persist after media change.
+
+In the formatted area of the media, coarse random access is possible.
+For DVD-RAM and DVD+RW write addresses and data size need to be aligned
+to 2 KiB. For DVD-RW alignment has to be 32 KiB. Within these limitations
+the write address is at the discretion of the sending program.
+Just use 2Ah WRITE to send data.
+(mmc5r03c.pdf, 6.44)
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+The size of the formatted area can be inquired by 23h READ FORMAT CAPACITIES.
+The Number Of Blocks value in the Current/Maximum Capacity Descriptor gives
+this size in 2 KiB blocks. But this is true only if Descriptor Type is 10b
+("Formatted Media").
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.2.3)
+
+Not yet formatted areas may be completely forbidden or they may be allowed for
+sequential writing (DVD-RW Intermediate state) or they may be allowed for
+random access only after the necessary waiting time for formatting to reach
+the desired address (DVD+RW with background formatting active).
+
+Already written areas can be overwritten without special precaution.
+Blanking a DVD-RW actually destroys its formatting.
+
+
+Most of the concepts usually expressed in Write Parameters mode page 05h do not
+apply to the recipes here: Test-Write, Buffer Underrun protection,
+Multi-session, Write Type, Block Type, Track Mode, ...
+There are hints for multi-session formats with DVD-RW but both of my drives
+do not offer "Add Session" Format Types 12h or 14h.
+(mmc5r03c.pdf 6.5.4.2.7 , 6.5.4.2.9)
+
+
+Caution: Drive and media compatibility seems still to be quite an adventure.
+If you experience problems, especially problems with readability, then try
+different drives and media brands. Failure does not necessarily mean that the
+software did anything wrong.
+
+
+-------------------------------------------------------------------------------
+DVD-RAM, fully formatted DVD+RW or DVD-RW :
+
+Full format is the natural state of DVD-RAM. 
+
+DVD+RW reaches this state if Background Formatting is allowed to finish without
+being stopped by 5Bh CLOSE TRACK SESSION.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+The formatting state of a DVD+RW may be inquired by 51h READ DISC INFORMATION
+requesting Data Type 000b "Standard Disc Information". In the reply,
+BG Format 3 indicates fully formatted media.
+(mmc5r03c.pdf 6.22.3.1.13)
+
+DVD-RW reaches this state either by Format Type 00h (or 10h) with maximum
+size given as Number Of Blocks, or by writing sequentially until the disc is
+completely full into an intermediate session opened by format 15h resp. 13h.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.1, 6.5.4.2.10, 6.5.4.2.8)
+A fully formatted DVD-RW can be recognized by 23h READ FORMAT CAPACITIES. The
+Descriptor Type of the Current/Maximum Capacity Descriptor is 10b ("Formatted
+Media") and 0 blocks are offered with Format Types 13h or 11h.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+See also discussion of unformatted or partially formatted DVD-RW below.
+
+
+In fully formatted state there is no need for any formatting before writing nor
+for any finalizing other than forcing the drive's buffer to media by
+35h SYNCHRONIZE CACHE (which is mandatory for writing, anyway).
+(mmc5r03c.pdf, 6.41)
+
+(It seems to do no harm to send to DVD+RW or DVD-RW a 5Bh CLOSE TRACK SESSION
+with Close Function 010b despite there is no session open in this scenario.)
+
+
+-------------------------------------------------------------------------------
+Unformatted DVD+RW
+
+This is the state of previously unused DVD+RW media.
+
+The formatting state of a DVD+RW may be inquired by 51h READ DISC INFORMATION
+requiring Data Type 000b "Standard Disc Information".
+In the reply, BG Format 0 indicates unformatted media (or unsuitable media).
+(mmc5r03c.pdf 6.22.3.1.13)
+
+Formatting has to be started by command 04h FORMAT UNIT, Format Type 26h.
+Different from other format types, 26h allows to send a fantasy size of
+0xffffffff blocks and does not require the caller to know the exact maximum
+size offered with that format.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+
+As its name suggests, one has not to wait for background formatting to end
+but may very soon start writing as on formatted media. Random access to
+yet unformatted areas can last long, though.
+
+If backup formatting has been started at the beginning of the session, then
+it may get stopped after the final cache sync by 5Bh CLOSE TRACK SESSION
+with Close Function 010b. 
+(mmc5r03c.pdf 6.3.3.6)
+
+Formatting of DVD+RW is called "de-icing" because unformatted areas offer
+no hold for random access addressing and are thus slippery like ice. One can
+also see a color change from shiny unformatted to more dull formatted media.
+
+
+-------------------------------------------------------------------------------
+Partly formatted DVD+RW :
+
+This state is achieved by stopping background formatting before the media
+was completely formmatted. 
+
+The formatting state of a DVD+RW is obtained by 51h READ DISC INFORMATION
+requiring Data Type 000b "Standard Disc Information".
+In the reply, BG Format 1 indicates partly formatted media.
+(mmc5r03c.pdf 6.22.3.1.13)
+
+If the data of the session surely fit into the formatted area, then it would
+be unnecessary to restart background formatting.
+But in order to make the DVD+RW surely accept its maximum number of bytes,
+formatting may be restarted by command 04h FORMAT UNIT, Format Type 26h,
+with the Restart bit set and Number of Blocks set to 0xffffffff.
+(mmc5r03c.pdf, 6.5 FORMAT UNIT, 6.5.4.2.14 Format Type = 26h)
+
+From then on, the same rules apply as for previously unformatted DVD+RW.
+
+
+-------------------------------------------------------------------------------
+Unformatted DVD-RW (media profile is 0014h) :
+
+This state is present with previously unused media. It is also present with
+media blanked by programs cdrecord, wodim or dvd+rw-format and with media which
+were sequentially written from blank state.
+Profile transition from formatted 0013h to unformatted 0014h is done by
+A1h BLANK.
+(mmc5r03c.pdf, 6.2)
+Experiments on my drives indicate that only Blanking Type 000b "Blank the disc"
+achieves neat media. Media blanked via type 001b offer no feature 0021h and
+stall cdrecord or libburn already when those media get examined. growisofs can
+burn them - but only via DAO (feature 002Fh which prescribes Write Type 2).
+(mmc5r03c.pdf 5.3.11, 5.3.25)
+
+For becoming overwriteable such media need to be treated by command 04h FORMAT
+UNIT.
+(mmc5r03c.pdf, 6.5)
+The Format Type has to be chosen from the list replied by 23h READ FORMAT
+CAPACITIES. Suitable are Format Types 00h, 10h, 15h.
+(mmc5r03c.pdf 6.24)
+
+Format Types 00h and 10h provide a writeable area of a size given by Number of
+Blocks. Type 00h seems to be the most traditional and complete one. It needs
+no closing of a session at the end of writing.
+The Number Of Blocks may be at most the value reported by 23h READ FORMAT
+CAPACITIES in the entry for the desired format type. Full format is achieved
+by sending exactly the reported value.
+(mmc5r03c.pdf, 6.5.4.2.1 Format Type = 00h, 6.5.4.2.5 Format Type = 10h)
+
+Format Type 15h provides a writeable area of given size too, but this area can
+be expanded by sequential writing and afterwards marked as overwriteable by
+closing the session. It is even allowed to format with size 0 and to leave
+the size claim entirely to a sequential write process beginning at LBA 0.
+(mmc5r03c.pdf, 6.5.4.2.10 Format Type = 15h)
+When writing is done and cache is synced, one should send 5Bh CLOSE TRACK
+SESSION with Close Function 010b in order to bring the session out of
+Intermediate state. 
+(mmc5r03c.pdf 6.3.3.2.3)
+If not written up to the last 32 KiB block, the DVD-RW is only partly formatted
+after that.
+
+
+-------------------------------------------------------------------------------
+Partly formatted DVD-RW (media profile is 0013h) :
+
+This state is achieved by formatting a DVD-RW with a number of blocks which
+is less than offered for the Format Type by the drive's reply to 23h READ
+FORMAT CAPACITIES. If the media was most recently formatted by Format Types
+015h or 013h then it must have got written some bytes and afterwards treated
+by 5Bh CLOSE TRACK SESSION, 010b in order to be partly formatted.
+(mmc5r03c.pdf 6.3.3.2.3 CLOSE TRACK SESSION 010b, 6.24 READ FORMAT CAPACITIES)
+Elsewise the media is in Intermediate state. See below.
+
+A partly formatted DVD-RW can be recognized by 23h READ FORMAT CAPACITIES. The
+Descriptor Type of the Current/Maximum Capacity Descriptor is 10b ("Formatted
+Media") and the Number Of Blocks with formats 00h, 10h or 15h is larger than the
+currently formatted size, resp. more than 0 blocks are offered with Format
+Types 13h or 11h.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+
+If the data of the session surely fit into the formatted area, then it would
+be unnecessary to do any further formatting.
+But in order to make the DVD-RW surely accept its maximum number of bytes,
+partial formatting may be expanded by command 04h FORMAT UNIT, Format Type 13h,
+which is supposed to be offered by the drive in this state. This brings the
+session again into Intermediate state and thus allows expansion by sequential
+writing. As with Format Type 15h it is ok to set Number Of Blocks to 0, so that
+no fixed size formatting work is done and writing can begin soon after.
+(mmc5r03c.pdf, 6.5.4.2.8 Format Type = 13h)
+
+When writing is done and cache is synced, one should send 5Bh CLOSE TRACK
+SESSION with Close Function 010b in order to bring the session out of
+Intermediate state. 
+(mmc5r03c.pdf 6.3.3.2.3)
+If not written up to the last 32 KiB block, the DVD-RW is only partly formatted
+after that.
+
+Format Type 13h has been tested only with expanding sessions formatted by 15h.
+Nevertheless it is offered with sessions from 00h and 10h, too.
+According to the specs, Format Type 11h would expand a session by a fixed
+size. This has not been tested yet because it is less appealing than 13h.
+(mmc5r03c.pdf, 6.5.4.2.6 Format Type = 11h)
+
+
+-------------------------------------------------------------------------------
+Intermediate state DVD-RW (media profile is 0013h) :
+
+This state is achieved by formatting a DVD-RW with Format Type 15h or 13h
+without subsequentially writing data and sending 5Bh CLOSE TRACK SESSION
+with Close Function 010b.
+Such media behave very unpleasing with my DVD-ROM drive under Linux 2.4 ide-cd.
+One should therefore better avoid to release media in this state.
+
+This state can be recognized by 23h READ FORMAT CAPACITIES. The Descriptor Type
+of the Current/Maximum Capacity Descriptor is 11b ("Unknown Capacity") and
+no formats 13h or 11h are offered.
+(mmc5r03c.pdf, 6.24.3.2.1, 6.24.3.3)
+
+One may treat such media as if Format Type 15h or 13h had been freshly applied.
+I.e. sequential writing from LBA 0. After cache sync bring the session out
+of Intermediate state by 5Bh CLOSE TRACK SESSION with Close Function 010b.

+DVD-RW Restricted Overwrite    0013h
+DVD-RW Sequential Recording    0014h
+
+There are two approaches for writing to sequential DVD-R[W]: DAO and
+Incremental. Not all media and drives offer Incremental which allows 
+multi-session as with CD media and does not demand a predicted track size.
+DAO seems to be the older method. It allows only one single session and

+About overwriteable, blank, appendable and finalized DVD-R[W] media :
+
+DVD-RW can be either in formatted state Restricted Overwrite or in unformatted
+state Sequential Recording. Sequential media can be either blank, appendable
+or finalized.
+
+Only blank and appendable media are sequentially writeable. For overwriteable
+DVD-RW see the Overwriteable DVD Cookbook.
+
+Overwriteable DVD-RW can be detected by their profile number 0013h in contrast
+to profile number 0014h for sequential DVD-RW.
+The status of sequential media can be inquired like with CD by 51h READ DISC
+INFORMATION requesting Data Type 000b Standard Disc Information, where reply
+value Disc Status indicates:
+ 00b   blank
+ 01b   appendable  
+ 10b   finalized
+ 11b   others (unsuitable for this recipe)
+(mmc5r03c.pdf 6.22.3.1.4)
+
+Finalized, appendable or overwriteable DVD-RW can be brought into blank
+sequential state by command A1h BLANK with blanking type 000b "Blank the disc".
+See TAO Multi-Session CD Cookbook for details about blanking.
+
+After minimal blanking (type 001b) DVD-RW my two drives do not offer the
+Incremental Streaming feature 0021h the media any more. Full blanking (000b)
+brings back this feature.

+Incremental writing :
+
+Incremental writing allows to produce multi-session DVDs. It is indicated
+by feature 0021h being marked current in the reply of 46h GET CONFIGURATION.
+growisofs inquires 0021h by setting Starting Feature Number to 0x21 and
+Allocation Length to 16 in order to get only this one. The feature descriptor
+begins at byte 8 of the reply. Its availability is indicated by the Current

+structure. If another link size item is 16, then 16 is used.
+[*4:]
+growisofs takes Packet Size from 52h. Specs predict it will be 16 (= 32 kB).
+(mmc5r03.pdf 7.5.4.16)
+
+The writing process is much like in "Writing a session to CD in TAO mode" :
+Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION.
+libburn writes full 32 kB buffers via 2Ah WRITE.
+(mmc5r03c.pdf, 6.27 READ TRACK INFORMATION, 6.44 WRITE)
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+The track has to be closed by 5Bh CLOSE TRACK SESSION Close Function 001b.
+growisofs uses the logical track number for that and not FFh like libburn
+does with TAO CD. So libburn obtains the Last Track Number in Last Session
+from the reply of  51h READ DISC INFORMATION requesting Data Type 000b
+"Standard Disc Information".
+(mmc5r03c.pdf 6.3.3.2.2 CLOSE TRACK, 6.22.3.1.)
+
+Multiple tracks are permissible in a single session. After all of them have
+been written, 5Bh CLOSE TRACK SESSION Close Function 010b with Logical Track
+Number 0 closes the session. It depends on the Multi-Session value in mode
+page 05h wether the disc is finalized or stays appendable.

+(mmc5r03c.pdf 5.3.25)
+Experiments with growisofs showed that the track size needs to be predicted
+and may not be exceeded during the write process. (growisofs ran into SCSI

+(mmc5r03.pdf 6.27)
+[*2:]
+8 means: 2048 byte data blocks. growisofs sets this value if Data Mode from
+above 52h READ TRACK INFORMATION is 1 or Fh, which is predicted by the specs
+to be always true. (If not: growisofs aborts.)
+(mmc5r03.pdf 6.27.3.10)
+[*3:]
+Link Size, Packet Size and their companions only apply to Write Type 00h.
+
+The session layout must be described by 53h RESERVE TRACK, RMZ=ARSV=0.
+Reservation size should better already be aligned to 32 KiB. It has not been
+tested yet, what happens if not enough data get written.
+(mmc5r03c.pdf 6.31)
+
+Next Writeable Address is fetched from the reply of 52h READ TRACK INFORMATION.
+The reply is supposed to be 0. libburn writes full 32 kB buffers via 2Ah WRITE.
+(mmc5r03c.pdf, 6.27 READ TRACK INFORMATION, 6.44 WRITE)
+If the track source delivers less than the announced size then libburn pads up
+by zeros.
+When writing is done, it is mandatory to force the drive's buffer to media by
+35h SYNCHRONIZE CACHE.
+(mmc5r03c.pdf, 6.41)
+
+No further finalization is necessary. (I.e. no 5Bh CLOSE TRACK SESSION.)
+
+
+-------------------------------------------------------------------------------
+Obtaining DVD-R[W] multi-session info for extending ISO-9660 filesystems :
+
+Like with CD it is necessary to obtain the two numbers for mkisofs option -C
+in order to prepare a ISO-9660 filesystem image which by its inner pointers
+matches the block addresses of the future location on media.
+These are the start address of the first track in the last complete session
+and the predicted start address of the track which will host the new image.
+See TAO Multi-Session CD Cookbook for some more info about mkisofs aspects.
+
+
+The first number may be gained by 43h READ TOC/PMA/ATIP Format 0001b which in
+table 478 promises quick access via Start Address Of First Track In Last
+Session.
+(mmc5r03c.pdf 6.26.2.5 table 478, 6.26.3.3.1)
+Regrettably the MMC-5 specs still define a useless reply for non-CD media
+which obviously stems from MMC-3 times when no multi-session was possible
+with non-CD.
+(mmc5r03c.pdf 6.26.3.3.3)
+Both my drives do give a useful reply with the correct number for appendable
+DVD-RW. But not being backed by the specs this method appears unappealing .
+
+Another approach would be a formatted Table of Content, obtained by 43h READ
+TOC/PMA/ATIP Format 0000b. The specs do not totally outrule that this returns
+useful data with non-CD but they define a crippled TOC for multi-session.
+(mmc5r03c.pdf 6.26.3.2.4)
+My LG drive returns a more detailed TOC, my NEC drive stays with the rather
+suboptimal specs. So one would get different TOCs on different drives.
+Nevertheless, the MMC-5 compliant TOC would return the desired number in
+the Track Start address of the track with the highest number before AAh.
+
+Most stable seems the approach to obtain the desired number from the reply
+of 52h READ TRACK INFORMATION, Address/Number Type 01b. The field Logical Block
+Address/Track/Session has to bear the track number of the first track in the
+last complete session. To determine this number one has to determine the
+number of the last session and the number of the last track from 51h READ DISC
+INFORMATION and to iterate over the tracknumber by 52h READ TRACK INFORMATION
+until the first track with the desired session number appears and reveils
+its start address. 
+(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK)
+This method is very near to fabricating an own TOC. So libburn does this 
+when inspecting the media. If the first number for -C is needed, libburn
+inquires its TOC model for the address of the first track in the last
+complete session. See below for a detailed description of TOC fabrication.
+
+
+The second -C number is the exact prediction of future track start address. It
+is gained like with CD by 52h READ TRACK INFORMATION Type 01b. Different from
+CD one may not use track number FFh but has to use the Last Track in Last
+Session from 51h READ DISC INFORMATION. 
+(mmc5r03c.pdf 6.22 51h DISC, 6.27 52h TRACK)
+
+
+-------------------------------------------------------------------------------
+Obtaining a Table Of Content from DVD-R[W] :
+
+The raw TOC entries from 43h READ TOC/PMA/ATIP Format 0010b as described with
+CD media are not available with non-CD.
+There is a Format 0000b "Formatted TOC" but this is with non-CD a fictional
+information much at the discretion of the drive. Two drives with the same disc
+may well return different Formatted TOC. They are supposed to be consistent
+only about the last complete session and even there the MMC-5 specification
+6.26.3.2.5 seems to prescribe a structure which does not match the true
+structure of incremental writing to sequential DVD-R[W].
+(mmc5r03c.pdf 6.26.3.2)
+So i prefer not to use this method of getting a TOC.
+
+
+The alternative is to produce an own TOC from information gained by 51h READ
+DISC INFORMATION and by 52h READ TRACK INFORMATION which reveil a CD-like
+structure of sessions and 1:n related tracks.
+
+51h READ DISC INFORMATION Data Type 000b, fields Number of Sessions (Least
+Significant Byte) and Number of Sessions (Most Significant Byte) give the
+number of sessions. The last complete session number of an appendable disc
+is one less because there is an incomplete session at its end. libburn only
+records complete sessions in its TOC model.
+libburn uses Last Track in Last Session as a hint for the range of track
+numbers.
+(mmc5r03c.pdf 6.22)
+
+Next step is to iterate from 1 up to the last track number and to obtain
+the according track info by 52h READ TRACK INFORMATION. Each track tells its
+Session Number (LSB at byte 2, MSB at 33), its Logical Track Start Address,
+its Logical Track Size, and much more which is not needed for a fake CD TOC.
+One may analyze the track info more finely but for this special purpose
+it is enough to discard the tracks which do not belong to complete sessions.
+(mmc5r03c.pdf 6.27)
+
+At the end of each session libburn inserts fake leadout entries into its TOC
+model. Their start address is computed from the start and size of the last
+track of the session.
