But, yeah. I'm with "Him" on this one. If it's not the psu, then the HD is the only component with parts to make this sound during accessing.
Oh wait, did you leave a popcorn maker with kernels in there? That could be it.
you know what it is the hard drive and yes it is a WD 160gb.
But I have a 80gb seagate that also spins at 7200 and none of that noise.Whats up with this brand?Something else my mom had an hp before this one similar sound it was also was a WD.I want to replace the drive any ways it is too small I back up my dvds on it.
