He'd installed a new DVD writer and was having all sorts of erratic behavior as described in my earlier post. The other thing I've encountered is drives jumpered CS but non-CS cables. My current practice when building a new machine is to jumper M/S and use a non-CS cable. It has been posted on this list in past threads on this subject that jumpering M/S even with a CS cable will over-ride the CS - I have no direct experience with that. If I get a machine that has a cable select cable, I jumper both drives CS. But, to go back to what Joel was saying, he asserted that all sorts of problems with data corruption would occur if M/S were used. My experience hasn't been that - I've encountered extremely erratic drive behavior when encountering mis-configured systems, but the nature of that was drives being recognized sometimes, and other times, not, in a completely seemingly random manner - the systems were unusable in that state, and so there were no issues with data corruption, because the systems were dysfunctional. As to some MOBO's and some CS cables not handling CS correctly, I can't say I've encountered it, but, the possibility of it wouldn't come as a surprise; in 18 years of building and troubleshooting hundreds of machines, I've encountered many wild, and poorly implemented, pieces of hardware - my current pet peeve is USB implementation which is ridiculous. I'm dealing at this moment with a LaCie USB external mini-drive that has suddenly gone dark, which happens to have all my wife's website and video work on it.... Fortunately, it's backed up. -- Claude Jones Brunswick, MD, USA
