Hey. I got a 250 gb western digital HD (WDC WD2500JB-00REA0) this started about a week ago, i keep hearing the drive stop like being cut from power and then powering up again,i had my computer on for a couple of weeks before this started could this anyhow affected it. I also tested it with SpeedFan S.M.A.R.T function and it gave me this warning - "NOTE : your hard disk Power On Hours Count attribute current value (96) is below the normal range (97 - 100) reported for your specific hard disk model. Basically your hard disk was powered on for more than the maximum time the average user did. This means that either all of the reports collected are from hard disks that were not powered on for too long (this is realistic for recent models) or that your hard disk is becoming old. Usually this is not considered as a pre-failure advisory, but you should check whether you want to replace the hardware or keep an eye on its performances over time." Thanks.
