Hi!

I have a JMB363 myself and it has its share of problems.
I would say it is buggy hardware. (why would they otherwise
release a new windows driver every week ? if not to workaround
bugs in HW ;-)

My WD MyBook Studio Edition 500 GB external eSATA drive does not
work on the JMB363 correctly no matter what I try. Both
under linux and windows. I think the best was 30 minutes of
(apparent) error free operation under windows.

If interested, I can supply logs, data etc.
(I have a bunch of drives to try).

Regards,
David
