I didn't fancy spending $89 US on software to test a single 80GB disk, because I can buy a new one for about the same price. I googled for free tools, and found DFT by Hitachi. I downloaded the bootable CD version, and tested my disk with it. DFT didn't report any errors, and so I will carry on using the disk, and make sure I have good backups. The tool was easy to download and use, but I don't have any evidence about how good it is at finding errors - so far. DFT can be found at: http://www.hgst.com/hdd/support/download.htm
