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. Johan Ström wrote: > > On 23 jan 2006, at 09.53, Michael S.
