[PLUG] DVD-ROM Problem

[Robert McIntosh]

Hi,

I installed a DVD-ROM drive in a system that has a RH9 installation
(kernel 2.4.20-42.9).  Strange thing is, when I try to copy data from
the DVD-ROM drive, I receive errors from /var/log/messages (see end of
message for errors).  After a good long wait, the cp command exits with
a "cp: reading `filename': Input/output error" message.  Sometimes it
copies files and sometimes it doesn't - it's a rather erratic error.

Thinking this was a problem with hardware,  I replaced both the IDE
cable (yes...it is an 80-pin cable...although curiously the Sony DVD-ROM
drive included a 40-pin) and the DVD drive.  Same problem - even changed
to a completely different DVD-ROM manufacturer (it's a Lite-On in there
now...it was a Sony).  I checked BIOS configuration and all seems go there.

The DVDs were created by a State of Oregon department and has large (as in 2-3
GB) files stored on them.  I have no other problems with IDE devices (I
have two hds, and a CD-RW as well in the system...and yes the jumpers
are configured properly).

Please offer suggestions on what else might be at fault.  I have one
other suspicion that I hope someone can confirm.  I'll keep it silent to
not influence responses.

Thanks for your thoughts!
