Buffer I/O error on device hdc

["victor nawothnig" <victor.nawothnig@gmail.com>]

Hello.

I'm on Debian Etch and when I try to copy files from a DVD (which is
not scratched)
I get many errors like that in my syslog:

ATAPI device hdc:
 Error: Medium error -- (Sense key=0x03)
 Unrecovered read error -- (asc=0x11, ascq=0x00)
 The failed "Read 10" packet command was:

LastFailedSense=0x03 }

This problem occurred to me several times before on Gentoo,
but I was never able to track down the actual reason for this..
neither the DVD nor the Writer is broken, same goes with
the IDE cable. I'm 100% sure the hardware is intact.

With Gentoo my problem was somehow solved by upgrading
udev to 090, but I'm using 103 right now, so I guess that is
not the problem. I was rather thinking of something kernel
related..

So I was hoping if anyone of you could help me track down this
problem, since it appears many have that problem, but I couldn't
find any general solutions. Some appear to be related to ide-scsi
emulation, but ide-scsi is not even in the kernel in the Etch Repos.

Thanks in advance,
