I have a dell dimension 3100c and it has room for only one hard drive which is now full. Therefore I am going to buy a new hard drive and copy the contents from the old one to the new one. How would i copy a complete image from the old one to the new one as I think i can only plug one in at a time? I do however have a usb external enclosure for a ide drive but the drive in the computer and the drive I want to replace it with are sata drives. Any help would be apreciated. Thanks
