cdrskin -scanbus or --devices hangs for quite a while if there is
|
|
a CD drive which does not work properly (e.g. because it has individual
|
|
problems with DMA).
|
|
So if the superuser gets no result with cdrskin --devices then one should
|
|
disable DMA with the problematic CD drives
|
|
(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
|
|
and try again.<BR>
|
|
In severe cases it might be necessary to guess the device name /dev/sgN resp.
|
|
/dev/hdX of the non-ill burner if it cannot be found otherwise among its
|
|
ill peers. Alternatively one can guess the address of the ill device, remove
|
|
rw-permissions and retry the bus scan as non-superuser.

Enhancements towards previous stable version cdrskin-0.2.4:
|
|
<UL>
|
|
<LI>Option <KBD><B>-tao</B></KBD> is fully enabled.<BR>
|
|
SAO is still the preferred default but TAO is default if a track of
|
|
unpredicted size is present (stdin, named pipe, ...) or if a follow-up
|
|
session is written to an appendable CD.
|
|
(This is an intentional deviation from cdrecord defaults which themselves
|
|
have changed with the newest cdrecord versions.)
|
|
</LI>
|
|
<LI>Status report during blank, preparation and finalization improved.</LI>
|
|
<LI>Bug fixed: Trailing trash appended to .wav files caused error message
|
|
and, if exceeding fifo size, could even stall a burn.
|
|
(Workaround: disable fifo by <KBD><B>fs=0</B></KBD>)</LI>
|
|
<LI>Bug fixed: False speed with first pacifier cycle. Potential program
|

abort by floating point exception (NaN).</LI>

<CENTER><H3>About the relationship of cdrecord and cdrskin</H3></CENTER>
|
|
First of all: this relationship is single sided, as cdrskin has to be aware of
|
|
cdrecord but not vice versa.
|
|
<BR>
|
|
<BR>
|
|
I am a long time user of cdrecord and it works fine for me.
|
|
Especially i do appreciate its write mode -tao which allows to pipe arbitrary
|
|
data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well
|
|
maintained. So for me - there would be not problem with it.
|
|
<BR>
|
|
But the author of cdrecord and the Linux kernel people foster a very hostile
|
|
relationship. Ok, that's their business, not mine (or ours if you are with me).
|
|
One has to be aware, though, that this relationship might lead to a situation
|
|
where cdrecord is no longer available for certain Linux kernels.
|
|
<BR>
|
|
To have my own project prepared for such a time, i began to implement its
|
|
cdrecord gestures on top of libburn.
|
|
From now on i invite other interested users of cdrecord to teach cdrskin
|
|
the gestures necessary for their cdrecord applications.
|
|
Contact me. Let's see what we can achieve.
|
|
<BR>
|
|
<BR>
|
|
libburn and cdrskin are now mature enough to substitute cdrecord in its
|
|
major use cases of CD burning. It is possible to foist cdrskin on various
|
|
software packages if it gets falsely named "cdrecord".
|
|
I do not encourage this approach, but of course such a replacement
|
|
opportunity is the goal of a cdrecord compatibility wrapper.
|
|
<BR>
|
|
<BR>
|
|
It is very important to me that this project is not perceived as hostile
|
|
towards Joerg Schilling and his ongoing work.
|
|
I owe him much. For cdrecord, for mkisofs, for star. Chapeau.
