Albeit, I really had the hard drives working in full capacity when I was downloading a torrent, playing itunes, playing CS through crossover and searching the interweb with Firefox, while emptying my trashcan, but after all this, I heard the most nauseating hard drive clicking I've ever heard in my 14 years of playing on computers. I then hard rebooted my computer and all was fine and well. Do you think that this final sound and my previous complaints of file/folders going AWOL have something to do with hard drive failure that even the hardware tester failed to find? Has my iMac, which is no more than 6 months old, been shipped with a faulty hard drive? 
Or did I simply push the hard drive too far? Any thoughts welcome
