I've just been using the software that comes on the drive, or HD Tune Pro to do a full surface scan which does take a little less than a day, but i'm a windows guy. I'd still like to know how best to stress test or burn them in, but a guide like this one might just be the trick...but it doesnt seem to be much more than a deep surface scan.I'd like to know what tool as well and are you testing them before you pull them or afterwards?
