I recently bought a 2nd hard disk for my Taiwanese AT clone.
(Seagate 40Mb, fast, MFM).

I had no problem installing it, but after a short time I
started to get DOS "sector not found" read errors.
OK, I thought, run disktest from Norton to find the bad sectors, and patch
the files.

Anyway, to cut a long story short, I now have screen fulls of bad sectors
(about 100 bad sectors at last count and increasing all the time).
All the bad sectors are at the start of the disk,
and they seem to appear after I do a bit of concentrated work.
(eg trying to do a build).

I'm using a Western Digital controller (2FD,2HD), and somebody told me that the
old WD controllers can't cope with the faster drives and write bad sectors.
Does anybody know:
	Is this true?
	If so how can I tell if my controller is one of the old types?
	What can I do, short of changing the drive for a slower one and/or
	changing the controller?
