Hello,

in /var/log/messages I find tons of lines like:

Jul 17 11:20:42 venus kernel: hdc: tray open Jul 17 11:20:42 venus kernel: end_request: I/O error, dev hdc, sector 0 Jul 17 11:20:42 venus kernel: Buffer I/O error on device hdc, logical block 0

for several sectors and also for hdd (and then many similar message pairs of only the first two lines (without the Buffer I/O line...)).

What makes me wonder is, that (as far as I know)- there is no hdc nor hdd in my computer.

Don't you have a CD and/or DVD on that computer ?

I have an old CD writer and a new DVD writer.

do: ls -l /dev/cdrom /dev/dvd One or both should exist and be a symbolic link to /dev/hdc or /dev/hdd.

hdc should be the "master" device on the second ATA interface, and hdd the "slave" device on the same interface.

oh, I see...

If not too much time has passed since the last reboot doing this command:

grep hdc /var/log/messages | less

will show you all the messages about that device. The first few ones will show you its identification string, so you can find what it is.

oops, this gives me 2788 lines, starting April 6... But it doesn't really tell me much... First of all I havn't seen something like a program name that could tell me what wants access to my CD/DVD

...

...

That error could be some program trying to read a CD/DVD and not finding any (I am not sure abouth this).

Looks like if so. But how can I find out, which program? I havn't done anything that could ask for a CD.... The first message from today is: Jul 16 17:27:44 venus kernel: hdc: tray open But I havn't opened the tray nor did I do anything else with CD/DVD's today. The computer was running since early morning, but the first message today is from 17:27...

Can you use a CD or DVD when you insert one ?

Yes, I can read and write to CDs/DVDs just as usual (both drives work as they should)...

If you can I think you can ignore those errors.

well, ok. But anyway: I wonder what is looking after my drives without having my command to do so. Hey, we're not on Win here, aren't we? ;-) So, if anybody knows where/what I can look to find out more, I'll be happy for any hints. thanks and kind regards Daniel -- Daniel Bauer photographer Basel Switzerland professional photography: http://www.daniel-bauer.com erotic art photos: http://www.bauer-nudes.com/en/linux.html Madagascar special: http://www.sanic.ch -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
