I was hoping that this support article would have information useful
to fixing the driver (which I still suspect is the problem - endian problem),
but it calls out cable problems and drive utilities.

The same drives that are flaky on my Beige with the Sonnet temp card
(and drop back to Ultra/33) run fine - without hiccup - on the G4/AGP
on the internal busses.

I still think it's a driver problem with the wdc and/or wd driver.

(and no errors)

I could try using the cables from the G4 on the Sonnet card, but the cables
I'm using with the Sonnnet card are the cables that came with the card.
It would be pretty silly if Sonnet sent me inadequate cables.......
(I should try it....)
