[linux-help] CD-ROM errors

[Carl D Cravens <raven@xxxxxxxxxxx>]

I'm having trouble with a CD-ROM drive and wondered if anybody had any
insights. 

This drive is fairly new and I'm thinking that it's a "generic" 6x I got
at CompUSA cheap.  (I think it's a Panasonic, but I can't tell without
removing the drive from this 24x7 server.)  It's a standard IDE and it's
worked fine in my wife's Windows box for a few months.  

I recently installed it in my Linux server to do an upgrade (it's about
time I moved to Debian 2.1) and I get all kinds of read errors on the
console while trying to read from it.  It might get fifty meg just fine
and then starts getting driver-level errors.  I thought it might be the
CD's I'd burned on the funky Sony drive at work which gave me all kinds of
trouble when I first got it, so I ordered new copies from Linux Mall to be
sure... while I seem to get far fewer with the new CD's, I still get
errors.

Any clues?  Is this drive incompatible with the CDROM driver?  (I thought
I'd installed this system off this drive before putting it in my wife's
machine, but I could be wrong.)  Is my drive going bad?  As might be
obvious, this drive is the "master" on the secondary IDE controller (hdc),
there is no slave.  There is one drive on the primary controller.  It may
be that I installed with this drive as primary slave instead of secondary
master, but that seems unlikely, it being easier to hook it up as
secondary master (no jumper fiddling).  

Thanks!
