I had a Quantum Lightning 730 internal drive that was about 7 months old
that I had similar problems with.  It would work fine on the MacOS side but
under NetBSD it would develop medium errors and bad block problems.  I
would eventually end up testing and reformatting it with Silverlining and
it would work fine for a few weeks, then have the same problems again.
Eventually it developed errors that Silverlining was unable to fix.

Anyway I sent it back to La Cie where I bought it from.  I never found out
what was wrong with it because they "temporarily misplaced" it soon after
they received it. I never heard anything more about it, but I haven't had
any problems with my Quantum Fireball 1080 replacement.  Keep your fingers
crossed.  :-)
