Should I be worried then about the quality of the FW case? I tried the cable that came with my Western Digital 120 GB FW drive, I tried my iPod cable, and neither of them worked! I knew it was a cheap deal, and (next time!) will go with a Macally or better case. I'll see if I can find out where this cable was made, that is, the cable that works. John Pariseau
