My experience was a system that had been working fine but suddenly began getting weird problems, similar to what you have described, Anne. I spent several weeks trying everything I could think of since I knew the drive was good. If I had only one drive attached there were no problems, and if I put it in another machine there were no problems. Someone suggested moving the jumpering to CS so I did, and miraculously the problems disappeared. I have since used CS exclusively on those cables and have never (in more than 12 years) had a problem with drives. YMMV, but I have always had good luck using cable select in all that I do on PCs. > > > > The other problem I've heard about is > > http://linux.yyz.us/sata/sata-status.html#tx2 (SATA and PATA on the same > > Promise controller), which has a "preliminary patch" according to that > > site. > > > > But, in general, I haven't heard of any problems once you've got the > > machine working.
