I have a WD 80 gb drive, not the nice ones with the 8mb cache, just the regular old 80gb ATA 100 drive. Now this drive is about a year and a half maybe 2 years old. Now when the drive spins up, i get a kinda high pitched whirring sound. I thought it was the one of the fans on my video or mother board but when i put my ear close to my case i realised it was my HD. I ran chkdsk to check for bad sectors and it didnt find anything out of the ordinary, maybe 1 or 2. I havent had any of my other drives do this before, so Im wondering if i have a time bomb on my hands and my drive is going to crash or if there is something I can do to the drive (maybe something came loose) to get this to stop. I don't want to buy a new drive now if i don't have to. My monetary supply is tight as is.
 
I was going to look on western digital's site but it seems to be down for the time being.
