SUMMARY: help needed with HP 4mm DAT

My original question is listed below. Basically I had two problems

        1. mt -f /dev/rst0 returned that the tape was an exabyte 8500.

ANSWER: from Jochen Bern []

        strings - `which mt` | grep xab returns:

                Exabyte EXB-8200 8mm
                Exabyte EXB-8500 8mm

It appears that mt has the contents of stdef.h and st_conf.c

        2. Dumping to the new drive using "dump" was causing SCSI
           errors, but "tar" and "dd" worked fine.

ANSWER: from your truly
        SCSI cable length. I moved the drive to the second scsibus
        with far less cable length (ie 0) and it worked like a charm.

Don't know why dump was exposing the problem though.
