Hubert,
The first thing that comes to mind is checking the sector size of
the CD drive. I don't recall what sector size SHOULD be used (either
512 or 2048) but this may make a difference.
Is this the HP 6020 CD writer drive? I've never tested writers
on an INDY before. If so, do you have a CD-ROM to test with?
I don't know how to interpret the error messages received, so I can't
suggest what they might mean either.
Perhaps someone else on the list has more experience or information
with such a drive.
Sorry I can't suggest anything further :/
