PNY USB Drive not recognized

Hey everyone,

I tried doing a few google searches to find a resolution to this problem, but nothing that came up seemed to work, so I'm throwing this question out there.

I recently bought a 16GB PNY metal attache for my 2011 MacBook Pro (OS X). That computer fails to recognize the drive. Here are a few notes:

1. I tested the drive on a windows vista computer, and that computer recognizes the drive. I can read/write from it on that computer.

2. Neither USB port on my apple is faulty; other USB devices function fine via both ports.

3. I have tried several solutions including:

a) Restarting

b) Powering off, unplugging the power cord, waiting 15 seconds, replugging the cord, and booting up the computer

c) Restarting WITH the drive in the port\

d) Leaving the drive in for a while to see if it would eventually recognize it (no results)

e) Reformatting the drive to FAT32 to make sure it's possible for my mac to read/write from it

Please let me know if you have any suggestions as to what may be the issue. It's clear to me that the issue is neither a faulty port or a faulty drive, but rather some software issue between the drive and my mac.
