A word of warning, the "inertial rotation" procedure was great for
smaller drives, but you may break your arm applying this to an ESDI

Not necessarily.
Not all ESDI drives are physically large.
In one generic PC, I used an ESDI drive, that I bought used, with a WD -7

It has been a long-time (almost 40 years now) since I worked part-time at an
IBM dealer, BUT attended ALL the IBM hardware training (and later as an early
