We had this same conversation some months back, with pretty much the same 
staunch positions being advocated. I build lots of machines, that's part of 
my job. I'm with the above. This has been my experience. Someone stated that 
ALL cables are CS now - I'd be curious to see the basis of that info. It's 
not been my experience at all. Someone else stated that all drives are being 
CS enabled or something to that effect - I buy lots of drives, and that is 
not my experience at all, here in the U.S. I think the standard is 
increasingly being met, and newer equipment is tending to adhere, but if you 
have to deal with a lot of older machines and suppliers, you'll eventually 
run into the anomalies descrbed by Mikkel. I have, and so described them some 
months back. It was certainly a suggestion worth making to Anne...and as we 
see, her results were anomalous, just as Mikkel, and I, have suggested can 
be...
