Thanks for the information. I wish growisofs be distributed with some FAQ. Moreover, in case of error, in addition to technical information, I think it should give practical information about what could be wrong. > The capability to write DVD+RW deteriorates much later > than the capability to deal with DVD-RW. After getting problems with DVD-RW, this is also what I've read. I've also noticed that there are many Debian bug reports concerning DVD-RW, but not DVD+RW. Now, when I burn my old DVD+RW's (purchased in December 2005) with the same drive, I get I/O errors when I re-read them, though they have been burnt only a few times. > > I suspect that the blank command actually failed (but why?), > > READ DISC INFORMATION: > > Disc status: appendable > > ... > > READ TRACK INFORMATION[#2]: > > Track State: invisible incremental > > ... > > Free Blocks: 1480416*2KB > > Indeed the medium is still reported by the drive as being ready > for more sessions (e.g. by growisofs -M) of up to 2.9 GB. > I.e. blanking did not have the normal effect. Maybe a bug in dvd+rw-format, which should have detected the error (the 0.0 for 10 minutes was suspicious). > > > You may also try to format it, > > That's much better [...] I'm currently burning it, with no errors. > > Let's hope that it is entirely readable. With the same drive, everything is OK, by reading the DVD entirely and comparing. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
