kuro: lol! :o) randy, the 180 GB thing has to do with the max limit in most versions of Windows (I don't know about XP) - max 180 GB on a drive. To access beyond that without an instant massive crash you need a special driver from the HD manufacturer that allow access to the upper ends. Once you have it you're OK as long as nothing above the limit needs to be accessed during boot. Apart from that, there's nothing special about the big drives. In fact, really modern dirves run quieter and cooler than polder ones even though they may be much higher capacity. The main reason driver fail is heat. Probably 90% of failures are due to insufficient system cooling - so I seldom feel much sympathy for crashes - you don't have the fans, you shouldn't run the drives. My main system with 5 HDDs has a total of 8 (EIGHT) fans, 2 on PSU, 3 on chassis, 1 on CPU, 1 on GPU and 1 on bridge. So I keep temps down. Also, if you don't have the backup, you shouldn't run the drives. Like the guy said: Data of which there is only one copy doesn't exist at all. :] Fish
