Hitachi SimpleTOUGH

Excellent – this hard drive is great. it requires no external power, so all you do is take the usb lead out from the underside and plug it straight into your computer. there is no need to have to put any computer program in to run it, it just gets recognised by your computer and you can just start to put files on it. it is a rugged style of hdd. i have dropped it off the table onto the tiled floor, it bounced upon hitting, then i plugged it in and it works no problem. can use it outdoors or in tricky situations like on a laptop etc. nothing wrong, great.
