I'm coming in very late here, and only have some
hearsay. But, a friend of mine has built a new hobby
machine, with twin 160G drives on a 3Ware 8006, working as
a stripe. He had a bunch of problems with stability of the drives
until I gave him a couple of tiny (half size) jumpers, that he
put on the drive. Smooth sailing since them. If needed, I can find
what the jumpers did. But looking through the controllers doco
should give you a clue.
