ST506 maybe but ESDI was around for a bit longer than that - IIRC ESDI
made it up to 1G full-height 5.25" before dying completely.  I had a
330Mb half height ESDI for a long time - long enough that I got bitten
by someone deciding to use the alt status register in wdc effectively
breaking my system.  This was some years back though.

Is there any way we can #ifdef the code without making it too gross?

Cannot argue with that :-)  ESDI may be still alive out there
somewhere though.
