>Description:
This is an ATAPI Sony AIT-1 drive (SDX-420C) connected through a USB->ATAPI bridge in a LaCie enclosure.

When attempting to issue basic mt(1) commands such as rewind and offline etc. I typically get these errors:

# mt rewind
mt: /dev/nrst0: Invalid argument

Looking through the kernel messages these show up:

Nov 18 22:38:57 localhost /netbsd: st0(umass0:0:0:0):  Check Condition on CDB: 0x15 00 00 00 0c 00

Nov 18 22:38:57 localhost /netbsd: 
Nov 18 22:38:57 localhost /netbsd: st0: cannot set selected mode

The same error happens for any command or any use (such as with tar, etc.) for this drive. It gets detected as such:

NetBSD/amd64 4.0_RC4 (though have seen problem in 3.1 and 4.0_RC3, too, including i386):

I attempted and failed to turn on SCSIPI debugging to try and get further with this.
