My first NetBSD box was a 386-16 with 4MB and ESDI drives on a WD1007(?)
controller and a Micropolis 1355 (170MB disk)... I later moved to a
Maxtor 4380 and later still a Maxtor 8760... All of those drives handled
identification properly and reported correct geometry and size information.

I also used an Ultrastore ESDI controller at one point and the identification
worked through it as well...
