Thank you for the suggestion. I just tried:
# dd if=/dev/cdrom of=file
and got a clutch of errors like:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dec hdc, sector 1904, 1912, 1920, etc in turn
What does that mean ? The result produces a file 901120 bytes long, when
the original ISO file is 987136 bytes long, but at least at the front they
look pretty identical to 'od -c'
When the drive is mounted, all the files on the CD seem OK and don't
generate any media errors.
