Peter, Same cable, but I've got others to try with the system. And never less or more than 4 retries. Parity was enabled on the 1542 that was used .. I'll revisit the drives to verify they all have parity enabled as well. Don't have a good source to high quality SCSI cabling you know off, I'll I can get my hands on are the standard cables .. I've heard tell of some high quality cables that will certainlly help. Thanks for the prompt response. Randy On Sun, 12 Mar 1995, Peter Dufault wrote: > Randall S.
