I have a Seagate Freeagent 250GB external HDD that was formatted for the Mac. So, I instead went to disk utility, then erase, then went to MS-DOS(fat) and let it partition it for Fat32(right?). But, my PC doesn't detect the hard drive. Neither does my PS3. When I right click on the partition in disk utility it says format: fat32, but none of my devices can detect it. Any idea on what to do?!????
