In message <40llt4$out@darkstar.UCSC.EDU> - davidb@cats.ucsc.edu (David N 
Barne:>I bought a used Exabyte 8200 2.2Gb SCSI tape drive yesterday and
:>am trying to determine if it's got a problem or not.
:>
:>It is recognized just fine, and can read the old data on the used tape
:>that came in it, but when I try to tar or dd to it, I get a I/O error
:>after a certain number of records, that number varying dependant upon 
:>the block size I set.  dd fails with a message like:
:>
:>	# dd if=bigfile.tmp of=/dev/rmt1
:>	dd: /dev/rmt1: I/O error
:>	541+0 records in
:>	540+0 records out
:>	#
:>
:>Tar fails similarly.  (/dev/rmt0 is a well working Tandberg 3600 QIC drive)
:>
:>So I'm trying to figure out what's going on here.  Is there a proper
:>block size I should be using, or is it perhaps that the tape drive
:>has a problem, or what?
:>
:>Any hints, suggestions, pointers to help, etc. would be much appreciated.

:>BTW, I'm running Linux 1.3.11 on a Pentium 75 Mhz, ASUS Triton based mb
:>with the included NCR SCSI interface.

I'm not positive this is your problem, but when trying to use 
this drive under OS/2 Warp, with Back Again/2, I had problems, 
and the software company advise that the drive was not totally
SCSI compliant. They advised to update the ROMs in the drive.
NB: The drive still didn't work with their program. It does work
fine with programs that directly support it.

You might want to talk to Exabyte about it.
