Last time I installed a drive, it was a 72Mb drive by Micropolis.  One
of the procedures you had to do was run the IBM diagnostic program (this
was an AT, but I expect a PC has a similar procedure) and tell it what
"type" of drive you had.  It's a number, usually 1-6 I think.  The number
is stamped on IBM disks -- with ours, the documentation told you what to
set.  I think that the diagnostics program informs the drive controller
what to make of the drive.

If the PC doesn't have something like this in its diagnostics, check the
drive controller documentation and it probably will fill you in.  It may
be a dip switch setting.

Actually, if the drive installation documentation didn't tell you how to 
do this, you should complain.
