I was working on a computer when all of a sudden the computer restarted, and I got a message saying "PLEAse insert boot device" or something. I went to the bios setup to make sure that my hardrive is detected and that it's my boot device. MY motherboard did indeed detect my hardrive correctly. And the red button indicating harddrive activity was working. I decided to format my harddrive, but the drive c: could not be found by DOS. I took out the hardrive and inserted it into my other computer (newer one) but the harddrive still could not be detected neither by DOS nor by Windows, but motherboard did detect it. The harddrive also doesnt seem to have any noise coming from it. I checked the harddrive and none of the pins were bent or anything. I've been using that harddrive for 3 years, maybe the age screwed it over..... . PLease tell me what I should do. THanx.
