Thanks for your help on the Quantum SCSI HD. Did the low level format, also did, in fact, run fdisk, and reformatted but still wasn't accessible or addressable. Your comment, though made me redo them all and it proved fruitful. Spent the last 48 hours fiddling with the SCSI system and no sleep, so your reminder helped. This was my system with the financial data and critical to resolve.
This for your reminder which triggered me to redo all (after rechecking and fixing the termination problem).
Groggy but grateful, please post anything so I may accept and pay.
Thanks again for your help, Dennis.
