2 matching ext. drives but only one shows at a time

I have 2 WD external 1TB usb hard drives that are exactly the same. I have had them both plugged in at the same time in the past just fine and both shows up. Now when I plug them in only one will show at a time... whichever one is plugged in first is the one that shows. The other makes the connection sound but will not show up in windows explorer. (I can plug in other makes of external drives and they show fine.) I have tried manually changing the drive letters. However it just labels each one the same drive letter when I replug them back in. I have tried renaming the drives... making sure they are not labeled the same. Still does not work. Its like it thinks they are both the exact same drive. Any other ideas would be greatly appreciated.
