Buggy DVD-ROM behavior on SUSE 10.1


Hello,

I recently got openSUSE 10.1 set up on a new x86_64 computer, and am having trouble getting things moving, particularly with the DVD drives (this machine has 1 DVD-ROM, and 1 DVD-/+RW).

Sometimes drives don't mount at all, and other times they mount, but suddenly fail during data transfers (from DVD to hard drive). When the drive fails, I can click on it in KDE, and it acts as if nothing is wrong. I get the same problem at the console if I try copying data off of it. I even manually mounted the drive, and the same result occured.

Is anyone else having these same problems? It isn't the drive, as it works fine in Windows (it is a dual-boot SUSE/XP box).

I'm also seeing a lot of this in my kernel output:

hda: rw=0, want=7151388, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7151392, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7151388, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7151392, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7153700, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7153704, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7153700, limit=553000
attempt to access beyond end of device
hda: rw=0, want=7153704, limit=553000

and a lot of this...

I installed OpenSuSE v10.1 about a week ago and I had trouble with disk accesses. It turned out to be a problem with the Reiser file system on both the system partition and on an external USB disk. Is /dev/hda your system disk or DVD?

Try this on your hard disk partitons. This fixed my problems. Remember that you always unmount partitions before you run fsck. In my case I had a dual boot with SuSE v9.2 so I ran that to fix the v10.1 disk partition. If you have a live cd then you will be able to fsck your system partition.

Code:
/sbin/reiserfsck /dev/hda1
Error: unable to access block 108340
echo 108340 > badblock.txt
/sbin/reiserfsck -B badblock.txt /dev/hda1
Error: unable to access block 108341
echo 108341 >> badblock.txt
/sbin/reiserfsck -B badblock.txt /dev/hda1
Then when it finally completes successfully run reiserfsck --rebuild-tree.
Code:
/sbin/reiserfsck --rebuild-tree /dev/hda1
Since I had the same problem on an external USB drive I fixed that by changing to the XFS file system. I don't think I'll use Reiserfs again. I still have Reiserfs on my system partition but all of my other partitions are now XFS.

/dev/hda is my DVD. This machine has 2 serial ATA hard drives, so they are /dev/sda and /dev/sdb.
