Good idea. Adaptec have the 1210SA for around £40 which might fit the bill.

You could well be right as we suspect something very weird going on with the
cards. I told IT to bite the bullet and buy a replacement Adapatec SCSI
adapter (we could do with one as a spare anyway) and it arrived. Plugged in
the tape drive worked fine. Plugged in the existing SATA RAID and it hung on
boot up. After a considerable time unplugging, plugging and moving around
the server is back up and running. But as far as we can tell, we didn't
actually *do* anything except maybe change the order.

Cheers, Rob.
