SOURCE: PNY 8GB Flash Drive - PC Will not recognize. Have you installed a scanner/another external USB drive since first trying your Flash drive? If so, try unplugging that and re-insert your Flash drive. I had this problem and a friend suggested this and it worked! Posted on Oct 05, 2009.
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.
