Quickly and easily supplied by Memory King. After installing a relatively new WD Scorpio Blue 500GB hard drive, everything seemed to be fine. Unfortunately, the transfer rate was writing after a short time under a kB per second back. Even when reading large files transfer rate dropped after a few seconds away in the basement. Formatting also was not working. The format remained without error, depend. The incorporation of another older hard drive did not change. I had the same effects on three different computers. Possibly the electronics of the housing was defective or the hard drives needed, despite Y-cable, too much power. The case went back to Amazon. The rescission of the purchase was, as with Amazon common problems.
