Sorry in advance for the long post, but I'm trying to provide any
information that might be helpful for diagnosing the problem.
The following is on an existing installation that has worked fine for some
time now. I recently discovered that my DVD+-R/W drive will not even
mount data discs, shortly after updating my Debian testing installation,
though I am not yet convinced this has anything to dow with the update
Specifically I get:
[EMAIL PROTECTED]:~$ mount /media/dvdrw/
mount: I could not determine the filesystem type, and none was specified
However, if I specify all the options manually as root:
gosroth:~# mount /dev/hdb -t iso9660 /media/dvdrw/
mount: No medium found
And yes, there is a disc in the drive.
I think the reason for the difference in the error messages is simply the
fact that the type in fstab is 'auto'. Here is my fstab for reference:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/md0 / xfs defaults 0 1
/dev/sdb5 /backup ext3 defaults 0 2
/dev/sda5 /boot ext3 defaults 0 2
/dev/sda6 none swap sw 0 0
/dev/sdb6 none swap sw 0 0
/dev/hda /media/dvdrom iso9660 ro,user,noauto 0 0
/dev/hdb /media/dvdrw auto ro,user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
/dev/sdc1 /media/usbdev auto rw,user,noauto 0 0

/tmp /var/chroot/testing-ia32/tmp none bind 0 0
proc /var/chroot/testing-ia32/proc proc defaults 0 0
The disc I am testing with works perfectly fine in my other drive. Just
to be sure I tried a couple different discs and it's always the same
thing. Yet near as I can tell the drive appears to be working perfectly
fine:
