Does anyone know why an RQDX2 controller will not use
just any ST-506 interface drive, even if that drive is
physically identical (heads,cylinders,etc) to an RD53?
I know that an RD53 is a Micropolis 1325 and that you merely
change a jumper (R7) on the Micropolis to make the Digital
controller think it's OK (a real RD53). My question is, how
do you do this to a Maxtor 1085, which has the same head/cyllinder
layout? Anyone know this deep, dark secret?
