I'm using an Adaptec RLL controller with a generic (i.e., cheap) hard
disk in my Compaq DeskPro.  It works fine, and I'm now getting 30 Mb
instead of 20 Mb ... BUT I can't boot from hard disk anymore, since
Compaq's boot ROM (and Compaq DOS, too, but that's another story)
assumes 17 sectors/track.  RLL encoding gives 25 sectors/track instead
of 17.

It is better never to have been born.  But who among us has such luck?
One in a million, perhaps.
