Okay, i have a western digital my passport hard drive that i got back in august of 2009. so like a year and a half years old. well approximately 4 months ago all of a sudden it would start, windows would connect to it, then you would hear "click" and it would restart. and the process would repeat and repeat. then i've realized that it was the power, is there something i can modify in windows to fix this?

Ah, clicking sounds from HDDs often are indicative that it has bit the dust. I'm rather confused what was meant by "... then I realized that it was the power,"

Do you have another computer you could plug the drive into to see if it works?

yeah, i think it's only the specifically that computer because it works on the other computers.

Try connecting it to every available (USB or eSATA) port. Do other peripherals have issues?
