On a somewhat related note.. I have a 2940UW. Can I use a 50 pin Ultra2 drive on the 50 pin Narrow channel? I know I wouldn't get U2 speeds, but the 50 pin narrow channel is all I have to use. 68 pin UW is too expensive and hard to find these days. I can find 50 pin Ultra2 18 gig drives for pretty cheap. Thanks. Ian
