CD/DVD player - kernel error message

[fingal]

Hello guys and gals,

I decided to spend a bit of time looking at error messages in my /var and found that my Mandrake kernel is producing an error message for my Liteon CD/DVD player. Using Mandrake 10.1 Official release, Athlon XP 1800 chip. This player is a master device, the slave is an LG CD rewriter. The message is as follows:

Jan 8 20:08:24 localhost kernel: end_request: I/O error, dev hdc, sector 90 86000
Jan 8 20:08:24 localhost kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error }
Jan 8 20:08:24 localhost kernel: hdc: command error: error=0x54
Jan 8 20:08:24 localhost kernel: end_request: I/O error, dev hdc, sector 90 86004

This is the 'tail' of a very long file indeed! It's not critical that I solve this, as everything seems to work well on the surface. Maybe my firmware isn't supported very well? I've been aware of the above for some time, but am curious about what might cause this. I had a look at dmesg output and got:

hdc: JLMS XJ-HD165H, ATAPI CD/DVD-ROM drive

Which seems very normal to me... All comments appreciated, thank you.

Hello all,

Carrying on a tradition of replying to my own posts I've Googled around (I enjoy a good Google, don't you?) and found that this is quite a common problem. Reading between the lines, I think it's 'cos I have an 'out of the box' kernel... So far, I've avoided 'rolling my own' kernel ... Maybe it's time?

It looks like I might have to set up some options in 'make xconfig' if that's still how you do it. One posting I read said something like:

xconfig: ATA/IDE/atapi: multi-mode YES

Maybe I'm on the right track. Any ideas out there? Thanx ...

Errors in the message log despite properly running hardware is a constant aggravation for me. How can you trust something that's spitting out errors?

I've been using linux for many years, and I have many gripes. But this neither the time nor the place.
