I just bought a rounded ATA133 cable from bestbyte.net, and I noticed that the rubber connector guards kept slipping when I was bending them around my case, exposing the wires... Are all rounded cables like this, or did I just buy the crappy kind? Also, rounded cables are a bitch to bend around... not as flexible and foldable as IDE ribbons... is this the tradeoff for better airflow, or is it just bad quality?
