I am not a person who likes to have information handed to them but my past month of hard drive experience is either the worst luck in man kinds history or something I am missing entirely. I have a custom built windows computer along with my MBP, this computer had three hard drives in it. One 136gb Raptor, one 500gb Seagate Hard Drive and one 400gb Western Digital drive. Two weeks ago my computer reported that the smart status on the 500gb drive was poor and I should replace it. I use this drive for my music (among other things) which puts a lot of wear and tear on the the drive. I bought a seagate 500gb and three cradle/rack kits for 5.25" bays off newegg that would keep my drives cool and reliable. Once everything was up and running I proceeded to copy over the music and some other important files. After the successful transfer I still wanted to wait at least two weeks before sending the old drive in for RMA repair since in my experience bad things always happen to data that isn't properly backed up. After less than a day of operation with this new 500gb drive it started failing, it would not report its temp at above 10 degrees celsius and it was slower than all hell when reading data. I quickly bought another 500gb drive from newegg and had it sent 2 day mail. In two days time I had a new 500gb Western Digital drive. I completed a clone from the old (10 degrees Celsius) drive to the new 500gb Western Digital drive today. Now... Smart is again reporting that this drive and my 400gb are failing... Whenever I try to listen to music or play video back it stalls a lot.... I have purchased another two 500gb drives from newegg because I have lots of important files on these drives but I am about to go broke trying to fix this thing. Can someone tell me if I am missing something? I have never had this bad of luck with hard drives before! Can bad data actually cause S.M.A.R.T. to misreport?
