i hope you are writing from a scsi hard disk to a scsi cd writer. ide
drives are not fast enough.
also don't write from a network drive to a scsi writer. it can't get the
data fast enough, unless it makes an image first.
also try to make the problem smaller. just have those two scsi devices
on the scsi chain and see how it goes.
check the scsi termination. this is usually the most common problem with
scsi device errors.
also see if you can set your scsi card back to manufactures default.
sometimes a bad setting can cause problems.
