Once more a problem with the EXA-Byte:

We have a EXA-Byte 8200 and want to use it with a SGI 4D/20.
But when we try to tar some bytes we get messages like the following:

Oct 22 18:05:04 mira unix: NOTICE: SCSI tape #5 Uncorrectable media error
Oct 22 18:05:04 mira unix: NOTICE: SCSI tape #5 Unrecoverable error
Oct 22 18:05:04 mira unix: NOTICE: SCSI tape #5 had 2215 recoverable Errors

(Copied from the SYSLOG-file).
This occures after some 100 kbytes. Our first guess was, that we had 
bad tapes, but we've tried several new ones from Sony and Exabyte. It
seems not to be a problem of the SCSI-bus, since there are no errors like 
' sc0: Unexpected info phase, state 48 phase 46' or
' sc0,1: Resetting SCSI bus: stray interrupt error, phase 0x46, state 0x48' we
had before we changed the firmware.

Do anybody know something about this (are we doing something wrong, or 
has someone else the same trouble ?), please post or mail it directly to
'muenzel@tat.pysik.uni-tuebingen.de'

tanx in advance
