Is there anything other than the hard drive itself that would cause hard drive failures or crashes. I have had 3 hard drives on my computer and my computer is less than 3 years old. The first drive was 1.5 years old and had registry error issues and it kept running checkdisk but found no errors. I reformatted, but then got more registry errors shortly after, so I decided to buy a new drive. This drive lasted about 2 months and then it was extremely slow one day and locked up so I reset it. It wouldn't boot back up, so I tried to reformat it during the reload and it wouldn;t recognize the drive, so I used a 3rd drive. This one worked for a while and did the same thing. For whatever reason both of them aren't recognized when I try to reload, but if I disconnect them from the computer for a while and plug them back in they are recognized and I can reload it again with vista. I have tried reloading again, but with both drives they last a couple of months and then do the same thing where they lock up and when I do a hard shut down the drive won't boot windows and have to format and load again. Rather than continuing down this cycle of buying more hard drives is there something other than the hard drives that could be causing this?
