IDE is a very poorly designed/enforced "standard".  Many manufacturers
were making IDE drives already before it was really even decided what
the complete IDE standard was.  Consequently, not all IDE drives work
with exactly the same electrical characterstics.  This can make IDE
drives from different manufacturers behave poorly together, where they
work fine by themselves, for with other drives from the same
manufacturer.  I would guess this is your problem, although I could
just be blowing hot air.  Your mileage may vary...
