I appreciate that, but since his statement was that he had acquired a
Maxtor 2190 that he wanted to *convert* into a RD54 it seems a
reasonable presumption that it would be set for DS1 or DS2 and would
need to be reset. In formatting a 2190 on my MicroVAX 2000, that is all
that I had to do. T 70 recognized it immediately, and it was duck soup
from there on.

That would certainly ruin your whole day!
