FWIW, I have just inherited two 8200s, and I'm getting exactly the same problem. It appears to be related to the drive; I have two drives on the machine at the moment: sa0 at ahc0 bus 0 target 4 lun 0 sa0: Removable Sequential Access SCSI-2 device sa0: 10.000MB/s transfers (10.000MHz, offset 7) sa1 at ahc0 bus 0 target 5 lun 0 sa1: Removable Sequential Access SCSI-CCS device sa1: 3.300MB/s transfers The other drive has the same code as your drive: sa1 at ahc0 bus 0 target 5 lun 0 sa1: Removable Sequential Access SCSI-CCS device sa1: 3.300MB/s transfers The AIWA drive (DDS) works fine. Any command I send to the Exabyte does the same thing. I don't have the SCSI spec handy, but I'd guess that: 1. There's nothing very wrong with yout tape drive. It's a quirk (it's not understanding a relatively simple command) 2. It can be fixed. Since I now have two of these drives, you can expect it not to take too long, but I'm not making any promises.
