Good Day!

I have a 2010 Mac Book Pro that I just downloaded the neww OS X Lion for the upgrades ext... I haven't had any other problems exept that before I downloaded the Lion my Mac would recognize my external hard drive (WD passport).  And now it doesn't, I even go to the finder and it doesn't even show up under "computer"  to make sure there isn't anything wrong with my external hard drive I plugged it into another mac that doesn't have Lion and it would work.  Please Help because my external drive has everything 1TG of everything...

Thanks!!!

MacBook Pro, Mac OS X (10.7)
