If it isn't broke don't fix it. U likely have a perfectly good controller
for any ST412 type MFM HDD controller. Why would you even consider and IDE
or SCSI drive when there are many good refurbished MFM drives available at
capacities well above the 20 MB you are replacing. Personally I would
look for a Maxtor or a Quantum drive staying away from the stepper motor
types, like the one u are replacing.
Just Google, "MFM HDD drive for sale" Select anyone that claims an ST412
interface from a reputable vendor, I bet u can even find one in Italy :-)
If memory serves, Tom, the hard drive in a model 20 and 30 is indeed an
ST412 interface, but it's a 3.5" model. While not impossible to find,
they are quite a bit less common than the 5.25" variety--and probably
close to unobtanium in Italy.
