My Passport Ultra not visible in 'My Computer'

I used an Ultra 1TB My Passport external drive to back up my Dish Network recordings on my DVR and now when I try to see it in My Computer, on my Windows 7 PC, it just does not show up. Does anyone out there have any suggestions? Thanks for any help that you can lend!

UGH! SO sorry, that I posted this in the wrong forum! Is it possible to delete this forum request? Once again, so sorry to be such a dork, I’ll be more attentive next time!
