Hi all,
Some how I have managed to get one of my dvd-rw disks in to a state where it can't be reformatted / blanked. I performed a disk at once write to it using (I am using kernel 2.6.0-1-386 on a standard Debian testing box)
growisofs -dvd-compat -Z /dev/hdc -r -J stuff.tar
I then tried another write using the same command but writing other_stuff.tar and got the standard error about the disk already having an isofs. Reading the dvd-rw page though (http://fy.chalmers.se/~appro/linux/DVD+RW/-RW/) I thought I liked the sound of Restricted Overwrite mode so I ran the command
dvd+rw-format /dev/hdc
The format apparently went fine with no errors. However no when I try to write anything to the disk I get
Executing 'mkisofs -r -J stuff.mp3 | builtin_dd of=/dev/hdc obs=32k seek=0' :-( track is formatted for fixed packet size
So I tried to reformat the disk using "dvd+rw-format -blank /dev/hdc" (and with -blank=full) and get this
* DVD�RW format utility by <[EMAIL PROTECTED]>, version 4.8. * 4.7GB DVD-RW media in Sequential mode detected. * blanking .:-( track is formatted for fixed packet size
I have had a really good google for "track is formatted for fixed packet size" and the only reference I can find is in the source code and I'm afraid my c isn't that good :o)
Is there any way to recover this disk? Some secret option to force it back into a writable state.
dvd+rw-mediainfo gives this information:
