well, actually, it DOES imply 4096 byte clusters if the drive in question has 4
heads and has 1024 byte sectors.

again, I didn't need this to convince it to 'happen' with my home-drive

I don't, off-hand, recall; I *DID* use the parameters provided in the ZDS
documentation for the Miniscribe 2012 drive (they're in the PREP.COM section of
the manual).  And, no, I don't think I have a newer version of PREP than you
do, mine has just run amok.
