The following hardware combination works with Minix:
Compaq Portable with nec v20, Seagate st-251 hard drive
and Western Digital WD1002a-WX1 Hard Disk Controller.

A few hints, use the Western Digital superbios to low level 
format the disk.  Do so dynamically and use value of 821 for
the write precomp and reduced write current cylinder.  The drive 
has 820 cylinders and 6 heads. defaults work for all else.

After the low level format I used Disk Manager tm which came
with the Seagate to partition the drive.  Use the DM /m for 
manual and use just the partition menu. DO NOT USE DISK MANAGER
TO INITALIZE THE DISK.  This wipes out all the good parameters 
that the controller put out there and the Minix HD driver is going 
to look for. I set the disk up with partition one set for Minix
at 10 meg. 2 and 3 become dos drives d and e, and partition 4
is the dos bootable, c.  Don't forget to tell the low level format
program where the bad tracks are.

As I said, this all worked for me, and now Minix talks to 
my hard disk :-)}
