External hard drive made by I-O DATA with a capacity of 320GB. USB 2.0 connection, also compatible with PS3. Operation has been confirmed, and the hard drive spins, but there was no response from either the computer or the TV. I don't know the cause. There is no dedicated USB cable. (I checked with a USB cable I had at home) Numbers are written on the back with a marker. Please understand that this is a junk item. - Brand: I-O DATA - Model Name: HDC-U320 - Capacity: 320GB - Rotational Speed: 7,200rpm - Connection Type: USB 2.0/USB 1.1 - Supported OS: Windows, Macintosh - Features: PS3 compatible Thank you for viewing.
