Bought this product with high expectations, was seriously disappointed. I had moved a lot of data over to this drive, then played a few hours worth of gaming, saved my progress on top of auto saves, then shut off my console. Next day, this hard drive was "unformatted", losing all data and saves. I looked on forums to see how to fix it, "reformatted" the drive, shifted all data over, played again, and had the drive become unformatted AGAIN. This process happened twice more before I through in the towel and returned it.
Would NOT suggest this product to my friends.
