I got an i-ecko 8GB thumb drive from a friend and am not able to use it on my mac. From my windows based desk top I reformatted it to FAT32 and the mac still wouldn't recognize it. I decided to reformat it to NTFS, which my mac then recognized it, but obviously I couldn't put anything on the thumb drive. I reformatted it back to FAT32 hoping that it would fix the problem, but once again the mac would not recognize it. I made sure to check that the ports were working properly and they are. My windows desk top recognizes it and is able to store data. Any suggestions?
