[comp.sys.zenith.z100] z100 won't recognize hard disk

Hell out there -- got a curious problem.  Just purchased an old z100
with a 10 meg hard drive.  The drive is a miniscribe 2012, attached to
a standard z100 hard drive controller (as far as I can tell).  Now,
this is the trouble.  Prep works fine; initializes and tests the
drive, completes with no errors (appropriate jumper had been set).
Part works fine (after jumper has been set back).  detect (also known
as verify) works fine.  All of them access the hard drive just fine,
the red light goes on, and they seem to read and write properly.
However, when I attempt to format the drive from Dos 2.1 (and 3.1) I
get a "not ready error reading drive E; abort, retry, fail?".  Any
ideas of what could be wrong?  There's a set of dip switches on the
controller card; I have no documentation, so I don't know if they
might be set wrong.  Help!  Copies of hardware documentation for the
z100 winchester system would be very helpful, as would any ideas or
suggestions.  Thanks!
