DVD-RW
|
||||
|
||||
DVD-RW are usable if formatted to state "Restricted Overwrite". They then
|
||||
behave much like DVD+RW. See above.
|
||||
DVD-RW in state "Sequential" have first to be formatted by
|
||||
cdrskin dev=... -v blank=format_overwrite
|
||||
"Sequential" is the state of unused media and of media previously blanked
|
||||
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
|
||||
(Command dvd+rw-format -force can achieve "Restricted Overwrite".)
|
||||
|
||||
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
|
||||
from the drive and last several minutes. Depending on mutual compatibility of
|
||||
drive and media, formatting can yield unusable media. I finally always got
|
||||
them revived again by help of: cdrecord-2.01.01a23 dev=... -v blank=fast
|
||||
After some tries, they got converted into state "Sequential" from where a
|
||||
new try could be made to get them reliably into state "Restricted Overwrite".
|
||||
(A similar sequential blank feature with cdrskin is still to come.)

If there is sincere and well motivated interest, the cdrskin project could try

to employ growisofs as DVD burning engine. The cdrskin project would prefer to

wait for DVD support being included in libburn, though.

A very limited and specialized cdrecord-compatibility wrapper for growisofs

serves in my project scdbackup. It is not overly hard to make one that serves

some very few fixed use cases.

libburn and thus the cdrskin project are currently aquiring own capabilities

to burn to DVD media. For now restricted to DVD+RW and DVD-RW and to single

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
