I have a pile of disks that I suspect. Looking at the drawer, I see 8 of them. As I have time I test them, usually with dd: dd if=/dev/sd1c of=/dev/null bs=64k and try that a bunch. Usually I shake loose a few errors after a while. And of course, listen to them. Hearing many clicking noises for recalibrates in a row is another sign of impending death. For laptop disks I've used IBM/Hitahi's drive fitness test, and that usually works well, but earlier this year it gave a drive a clean bill of health, and the disk died about 2 weeks later. --STeve Andre'
