Just bought a new macbook air, and I'm trying to transfer over my pictures that were on my PC (I no longer have the PC) and are now on a flash drive. The drive in question is formatted in FAT32 (4GB). I also tried two other drives, one a FAT16 (2GB) and another a FAT32 (8GB), both of which worked. When I plug in the flash drive, it doesn't show up in Finder, like the other 2 do, but it does show up in Disk Utility. Do I need to reformat the drive or something? I tried it on a windows computer and it worked fine.
