I inserted a 2.5" HDD into this enclosure, but it was not recognized at all by either my Dell PC or my PlayStation 3 after connecting the it with the USB cable. I then bought an enclosure made by a different company, inserted the same 2.5" HDD, and it was promptly recognized by both the computer and the PS3. Clearly, the HDD was fine; the StarTech enclosure was the problem. This StarTech product was 100% useless and I threw it in the trash.
