mt stat gives me the same error.  But, when using /dev/nrst0 (not rst0)
for dump, restore, tar, and mt (fsf|rewind|offline), I have no problems.
I haven't tried using /dev/rst0 though.

This is with an Exabyte 8200, and NetBSD-1.0/i386 (and 1.0-beta and 0.9C)
on a 486dx-40 with AHA-1542CF scsi card. I've yet to sneakernet -current
home yet.

Mind you, when the SCSI pass-through ioctl is working properly (if it
is already, then great!), I'll encourage David Burren (<davidb@various>)
to get his tape_status command working with it. (I consider David our
local tape drive guru ;). I'm sure he'll be able to fixup mt stat at
the same time.
