CD/DVD ROM drive keeps disappearing

[fishface]

I have an Intel server running SLES10, it has a slimline CD/DVD drive, BIOS knows about the drive, and I can boot from from the SLES10 DVD.

SuSE knows about the device and has given it this: /dev/sr0

Now, for all my other SLES installs, whenever I insert a CD/DVD into the drive SLES auto mounts it, but for some reason this has stopped working on this server.

It does not show up in fstab so I cannot mount it, what is going on?

It use to work, but a colleague has been working on the server (installed mysql and bugzuilla) so maybe something happened there, but could be just bad luck.

could be bad hardware

Open up the server and recheck the connections if you can.

If dmesg is listing the drive, can't he try and mount it manually and verify the drive will mount, and if so, just edit fstab? The reason I'm asking is because of his statement about fstab. He should still be able to mount a working drive manually, even if there is not a fstab entry for that drive, right?

yep, "if"

however if udev isnt properly naming and symlinking it, there might be a deeper issue

If I boot the server with the SuSE DVD it starts up every time and starts to run the installer, so it would lead me to think that the drive is most likely Ok.

So...server1

Internal drive - SLES10 DVD does not work - most other DVD media seem to work on this drive though.

External drive - SLES10 DVD does work

On another server...

Same DVD as used for server 1 works fine for 2 other Linux boxes.

I've also tried another copy of SLES10 - same problem.
