That's basically what this error means, even if the drive works OK
elsewhere. Sounds like this PC/drive combination is having problems,
especially with the hanging problem. Off the top of my head:

Update SCSI card drivers.

Uninstall any extraneous drivers Windows or other software may have
installed.

Make sure ASPI is installed by running ASPICHK (installed into the
Retrospect Program Files directory).

Try a different tape in your drive.

Try the drive connected to a different PC with a different card.

If these don't help, please call us.
