Well, it wasn't the drive.  Must've had a brownout, cause the drive
formatted on my stock 7300 (1/2Mb, no DRUN, no ICUS).  Once I can
scrape up the $$$, I'll get a UPS.  But that's besides the point.

I *am* able to get the MAXTOR to format on the stock machine.
Unfortunately, it's formatted as the 67Mb size.  Almost 100 Megs of
wasted space. :-(

Can a WD2010 be functional but not work when it comes to formatting?
Could the ICUS board extend some things so far that it won't work?  I
realize that I had initial problems with the board - the ribbon cable
from the main board to the upgrade board was soo long (8 inches) that
I had timing problems.  Now, the cable is 2 inches long (plug
included).  The machine runs (well, ran) fine with the shorter cable -
the longer one gave almost 4 megs a day of HDERR's.  The ECO wires I
added to the board for the ICUS socket are all as short as possible.
They all are intact.  No spare loops :-)

Has anyone else had this problem?  Up until the mods to the main
board (about 2 years ago), it formatted drives.  Come to think of it,
I haven't needed to format drives since then.  Is anyone out there
willing to format the MAXTOR for me since I cannot?  :-)  Maybe
someone just wants to buy it?  It's only got 1 hour of spin-time on
it.
