I'm possibly/probably wrong, but I thought the ACB-4000 only needs the
parameters setting prior to format - I don't know it it has some form of
non volatile RAM (unlikely) or if it stores the params in the first sector
on the drive and then offsets r/w requests by a set amount (I know at least
one vendor's board did that) so that they don't get overwritten.
