2 Xbox systems connected to 2 different WD MyBook 4TB drives and having problems with consoles seeing drives detected. Before buying new drives I decided to try a new set of cables and they work great. Both systems recognized the hard drives right away and loaded a few games to test, and the speeds for me were the same as the original cable, not much slower than some say. Unlike some negative reviewers, I knew the cables were two different lengths (I actually read the description. Imagine that) which was exactly what I needed for my setup. Will buy again if needed.
