well, I decided to buy a new computer, so I took my old 640gb hdd and attached it to my new computer, as a secondary drive, and when it wouldnt come up in computer, I went to disk manager, and it showed up as a 173643384495.75 gb hard drive. Thinking I mest have gotten a great deal for the drive, or that something was really wrong, I turned it off, cleaned the sata ports, and checked the cablesit showed the samr problem, and it makes a click sound, then spins down, then back up. I dont need the data anymore, so this is more of an educational question if anyone else has the same problem
