Here's an odd one:
my 5.25" and 3.5" drives, both high density, suddenly stopped reading any-
thing but high density disks. They can't even format low density anymore.
I get errors like "data read error," or "DMA failure" (from Norton Safe Format)
and when I tried with completely new disks I got the same problems. The disks
I am testing with work on other machines, so I suspect they are in good
shape.

The company that sold me the machine (an Acma 386-25) is completely baffled.

Ideas? It would be a pain to invoke the warranty.

Thanks.
