formatting a Maxtor 1140

[Stacy Marsella]

A friend is about to install a Maxtor 1140 (140 meg, 15 heads, ~28ms)
on his Unix-Pc (which has been upgraded to 5.1).

However, owing to the drive's prior history, we must do a low level
physical format. (Which cannot be done with the Diagnostic Disk,
apparently??)

So the main question is:
    What is the appropriate interleave?
