I had a similar problem with my 520/1-Meg^ and Supra.  I first thought it was
my DMA extension cable (3 feet long), but when I hooked it up to a friend's
system, it worked perfectly.  (The test I used was rapid accesses to the HD
by reading, displaying, and writing picture files.)

The problem was a marginal DMA chip.  $35 for a new one cured my problem and
I haven't had any trouble since.
