I also tried the combination of a 72meg Toshiba and the 33meg Rodime with no
luck.  Remember, using any drive alone, even under heavy load, produces no
problems.  It's only when *both* drives are used that failure is induced.  Not
only that, but both drives must be under heavy load.  This is why I suspect
either a design flaw in the controller (WD1003) or bug in uPort driver.  DOS
never generates accesses back and forth rapidly between drives as far as I
know, so there isn't an easy way to test the controller separately.  Could ask
the Xenix folks who use a WD1003 I suppose.
