 Posted: Tue Feb 14, 2006 6:49 pm Post subject: DVD-R drive suddenly stopped working [SOLVED] |
 |
|
As of Feb. 05, my DVD drive was working perfectly under Gentoo, but now it refuses to mount anything even when I try it as root. I've tried mounting several different flavours of CD (RW, R, and commercial, data and video) and a DVD+R that was burned using K3B and this same drive. Under Windows (2K) the drive still works perfectly and will read the disks that fail to mount under Linux. The result of a typical mount attempt looks like:
| Code: | akio ~ # mount /dev/hdc
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
|
As far as I can tell, nothing in dmesg | tail is relevent:
| Code: | akio ~ # dmesg | tail

/etc/fstab (stripped of comments, proc, and some other irrelevant bits) is:
| Code: | /dev/hda6 /boot ext2 defaults,noatime 1 2
/dev/hda7 / ext3 noatime 0 1
/dev/hda5 none swap sw 0 0
/dev/hda10 /mnt/gdrive vfat noatime,umask=0000 0 0
/dev/hda11 /mnt/hdrive vfat noatime,umask=0000 0 0
#/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user,umask=0000 0 0
/dev/hdc /mnt/cdrom auto noauto,user,umask=0000 0 0
/dev/fd0 /mnt/floppy auto noauto,user,umask=0000 0 0
|
(I commented out the /dev/cdroms/cdrom0 line and added in the /dev/hdc line after this started happening because that change seemed to be helping other people, but no dice in this case.)
cdrecord says:

so the device is being seen at some level (and yes, it is a Pioneer DVR-108).
Unfortunately, I have no idea what emerge --update world might have done in the past week-and-a-bit to cause this (I do know I haven't changed my kernel). Help?
