I downloaded that and was NOT impressed. Most of them sounded the same, and it contained a very small portion of all the sounds I've heard. And it's really gimmicky to tell you the exact model of drive and what's wrong with it. Do we really care if it's a head crash or a bad spindle motor? Either way it don't work and we can't do anything about it short of mail it to them.
fwiw, my collection
has been slightly updated, and features not only bad hard drives, but good ones too, so you can compare. I tried to weed out the ones that were too similar sounding. Some of them are doing some really wild things. (some failures are a LOT more common than others, hence trying to dedup)
