FWIW, I have a Seagate ST225 (still zero bad blocks) with controller.
If I can persuade the old 386 to do a netboot I can test it.
Right now it'll fail on the identify (may fail earlier on the reset

We certainly do not assume IDENTIFY command, if exists, succeeds.

Crazy :)
Would look something like this (but with geometry handling and some setup
work)
