my external hard drive (WD my passport) not detected on my laptop

Hi
my 500GB WD Passport is not being detected by my laptop when plugged in (by USB). A LED at the side of the external hard drive indicates that it is being powered on even though the computer shows no sign of detection (no sound indication; nothing showing up in My Computer)
I can feel the drive motor start up.(the vibration).
my machine's BIOS detect the drive. but I can't see it in device manager.
my machine use other devices properly.
and I checked my drive in 2 other laptops( both was windows 7) and both failed to detect my WD Passport.
could anyone help me?
thanks

Hello nhaghjoo and welcome to Seven Forums.

It's possible that your external hard drive doesn't have a drive letter assigned. If you could post a screenshot of Disk Management it might provide a clue as to what's happening.
