One of my PC's has an old NEC 6x CD-ROM drive based
on the OTI9xx (can't recall the exact number, but it's
probably the same chip as yours - similar vintage ...).
Anyway, this shares an IDE port with a 4G Quantum
drive, and both drives work quite happily together! So,
perhaps your drive had a hardware or firmware bug or
else perhaps you were using the wrong driver (see
below) or _it_ had a bug. As you can see, drives of this
vintage (the 6x may in fact be a little older than your
10x), using this same IDE controller chip *can* work
properly and not interfere with another drive on the
same cable.
Now, regarding your driver - make sure it is for that
particular drive, not another drive using the same
controller chip! I know I tried a few different drivers,
all written by Oak for various drive manufacturers,
all using the same IDE controller chip, yet only
the driver from NEC (written by Oak) worked with
this drive! These days it's not such a problem,
because all drives _should_ now conform to the
ATAPI standard, but for older drives, you really
must use the correct driver!
