This comes ready and formatted as FAT32, which works perfectly with the PS3 to play movies off, my main reason for buying it. I use it with my laptop too to back it up. Usually you'll find that external hard drives are NTFS, but not this one.
With my item, the plug I received happened to be an EU one, not a British one, meaning I had to buy an adapter. I assume this is just a mistake and not common with the rest of them though.
The product itself is very sturdy and heavy. Not like other flimsy HDD's that I've had. The brushed grey finish is nice too.
The on/off switch is a great feature. It's nice to choose when to use it, rather than it being running constantly when plugged into the PS3 like my other HDD.
Overall, I'd highly recommend this item for any use whatsoever.
