Both disk 2 & 3 are identical external 500GB WD hard drives hooked up USB. However I got a new hdd drive today and when I went to disk management disk 2 is showing up as 593GB. It should only be 465GB in a single partition, and no unallocated space, just like disk 3.

What's the deal, disk management detection bug or is that drive about to take a shit?
 
Maybe, but it's appeared as a 500/465GB for years. Now it magically remembers it's a 640?

It's strange I'll admit (I have a couple of ideas - but just guesses) ......but the only way to see for sure is to try formatting the unallocated space into a partition......it wont hurt anything.

Does windows disk manager detect overlapping partitions?

Is this the correct size for 640GB?

Edit: Hmm, should be 596 GiB.

Perhaps Windows has re-enumerated the drives, and your new one (640GB raw capacity) has now been designated Disk 2 ?
 
I think it's blatantly obvious to backup or move any data from the drive before trying any format.........but figured I'd better mention it before I get blamed for anything. :)

Oh.....why don't you load up a Linux live distro, and mount the drive to see what IT says.......or any other drive utility (ultimate boot cd has a bunch) just to see if it matches what windows reports.
