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 controller. It was a 3.5" half-height 200MB drive. (my first ESDI, my first 3.5" HDD, and my first HDD over 100MB (I was using a lot of ST4096's in other machines))
