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.
