I think that GVP are using the same PCB for 33 and 50 MHz.

Nope, not true!

You also need a few different PALs.

Way too low! With a Quantum 40, you should see _at_least_
700K/s (DOS-level). Make sure the AT drive supports mode-2
or faster transfer rates. Slower drives may indeed appear to
be unreliable. The Maxtor LXT200AT is a very nice drive, for
example. I have never seen a read/write error on mine and it
is quite fast (much faster than the usual Quantums).
