I *finally* got around to installing my MS3085 and the WD2010 this weekend.
The WD2010 seemed to work fine with the stock 20MB drive I was using, so I
then put in the 3085.  Formatting with the new s4diags was no problem (except
for the missing loader on the diag floppy :-)  but the surface test started
reporting write data errors for 60-70% of all sectors.   I stopped the test
after about 10 cylinders, removed the sectors from the bad block table (by the
way, is there a *easy* way to do this???), powered down and reseated the WD2010
and reconnected the 3085 to make sure I had everything right, and tried it 
again; same results.  So I'm now using the 3085 with the WD1010 with no 
problems (bad block table now has only 12 entries after formatting with the
WD1010 and the original diag floppy).  So, is this a
   1) 3085 problem (don't think so, because it works with the WD1010), 
   2) WD2010 problem (don't think so, because it works with the 20MB drive),
or 3) a 3085/WD2010 interfacing problem  (I think I remember Jan Bagend 
	discussing this at one time...are these the symptoms you saw?).
BTW, my system is a P3..P5 7300 with 1/2MB and an 1/2MB expansion memory board.

Thanks in advance for any input,
