Hey everyone, got a question about my Cd drive. I'm running Mandrake 9.2, and it didn't destroy my drive during install, so I don't think I'm having the LG CDROM issues that I read about.

The drive has worked fine for days, I just installed last friday.
I've even burned cd's with it, I must've installed something that changed a setting somewhere, because now, when I insert a cd, or try to view the contents of my cd, the drive just freezes.
and the 'busy' light stays on.
the drive is listed as hdc: CD-RW BCE2410IM, ATAPI CD/DVD-ROM drive

Here's fstab:
/dev/hda1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda6 /home ext3 defaults 1 2
none /mnt/cdrom supermount dev=/dev/scd0,fs=udf:iso9660,ro,--,iocharset=iso8859-1 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,sync,iocharset=iso8859-1,codepage=850,umask=0 0 0
none /proc proc defaults 0 0
/dev/hda5 swap swap defaults 0 0


When I look in the logs, I'm also seeing this:
ov 28 21:00:52 localhost kernel: cdrom: open failed.
Nov 28 21:00:52 localhost kernel: sr0: mmc-3 profile: 0h
Nov 28 21:00:52 localhost kernel: cdrom: open failed.
Nov 28 21:00:52 localhost kernel: sr0: mmc-3 profile: 0h
Nov 28 21:00:52 localhost kernel: cdrom: open failed.
Nov 28 21:00:52 localhost kernel: sr0: mmc-3 profile: 0h

anyone have an idea what's going on?
thanks again.

What burner prog are you using for the drive? It might have been guessing a little optimistically and given it something that the drive doesn't like.

Also, even though the logs are good, "dmesg" is a lot more verbose. You might want to drop some of that in here.

This is probably going to be some voodoo oriented solution... warning you ahead of time.

Cheers,

I was using K3B, But A few days later I installed Crossover office, and during my photoshop install, it told me the supermount/cdrw config wasn't right for what it needed the cdrw to do. and it asked me if I wanted to save some changes to fstab. I don't think I made the changes, but I'm not sure. I also installed vmware, which I know sometimes has issues with cd drives.

here's dmesg:

I can't find anything odd about that... buggrit. Google's got nothing, that's just a profile type and it just seems to keep getting reset over and over. So its not really debugging info in that regard.

What's resetting it would be the bug I figure.

The log you posted looks like /var/log/messages, you might want to see if there's anything in /var/log/syslog.

k3b is pretty, but it does buggy stuff sometimes... if I remember right there's an option to expand the burning window to have verbose output, but that might be useless as k3b if I remember right stops logging there after the burn when your error kicks in.

What's /etc/fstab look like? I doubt its there, but it might be as simple as that.

What are the permissions on the device? Its probably /dev/sr0 or /dev/scd0, etc... /dev/cdrom is probably just a symlink to /dev/sr0 I doubt its that too.

k3b also loves to use cdrao, which does some buggy stuff, it always caused my el cheapo burner to coaster. gcombust and xcdroast didn't have that problem. See if you can re-create the problem with either of them especially xcdroast as it does keep a verbose logging window open...

That's about all I could think of... hopefully a few good places to start.

Also, if you just want to try it from the command line... cdrecord by its bare self has a verbose option. Then if this creeps up after cdrecord exits then it would seem to be a scsi driver problem.

Cheers,

Finegan

yikes. this is out of hand. the rabbit hole goes deeper....

Ok.. I've found a whole bunch of links that lead to nowhere.

/dev/sr0 AND /dev/scd0 both link to: /dev/scsi/host0/bus0/target0/lun0/cd

/dev/cdrom links to:/dev/cdroms/../scsi/host0/bus0/target0/lun0/cd
there's also an entry for cdrom0 that links to the exact same place.
running

cat /dev/scsi/host0/bus0/target0/lun0/cd

Makes the drive check for a cd, however it still can't see the CD,It tells me "no medium found" and the busy light just stays on, and the drive freezes, keep in mind, I'm not trying to burn anything at this point, I just want to be able to view files on the cd.

fstab, I'm not so sure how to read it,
/dev/hda1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda6 /home ext3 defaults 1 2
none /mnt/cdrom supermount dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-1 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,sync,iocharset=iso8859-1,codepage=850,umask=0 0 0
none /proc proc defaults 0 0
/dev/hda5 swap swap defaults 0 0

why does it say 'none' before the Cd entry?
It's getting frustrating, I'd like to be able to get some work done with my PC, not spend all my time working ON it. ya know?
I think that's the reason some people stay with windows. But, I'm tired of windows, I see so much more potential with linux. Oh well, off to do more fiddling with it.

That is because it is not yet mounted. Supermount takes care of that for you, well most of the time anyway.

Change the cdrom line to read

instead of that scd0, unless it is a real SCSI drive. I would reboot to make sure it takes effect.

Supermount sometimes does weird things.

Later
