Brad,

Thanks for your reply.  We did have a bad cable and the tech fixed it
but maybe it is still bad - I will get a replacement and try it.  Also
we are using BusLogic BT-958D Wide PCI SCSI adapters (one to the STK9714
and a DLT7000, another to two DLT7000 drives) and we have begun to
wonder whether we should use other adapters.

All further suggestions are welcome!

Thanks.

Allan.
