To use my Archive Viper, I do first

   mt fsr 1
   mt rewind

and sequent accesses with mt, tar or dump work fine. I guess, this kind
of "initializes" something, err, or maybe not...

I have no idea why this helps, but without these commands, I get the same,
or at least similar errors from the SCSI device. Maybe I should have
reported this earlier, as I had this behaviour through all versions of
NetBSD since I have the tape (probably NetBSD-1.0 or -1.1).
