Hi i bought a new western digital 1tb Green Caviar Hard drive . . Here is the problem .. When i instially conencted the hdd and statred using it , there was absolutely no sound from the drive , and i belived it to be like that way all the time , until the same time , i switched of the pc to connect my old drive as a slave . . Just when i turn on the pc , there is this sharp noise from the drive as if it's reviving the power and the spindle is turning , that is wat i could make out by the sound. I managed to get the drive replaced , but again , when i first connected the replaced drive initially there was no sound until my father was using the pc . i came home from work ,turned it on , i hear the noise ! WHAT IS THIS THING ? IS THIS NORMAL ? and Yes , no cables are touching the fan inside , and there is no conflict as such ! HELP ME !I'm starting to belive that WESTERN DIGITAL SUCKS !
