Hi, So I have an older MBP 2.2GHz Core 2 Duo, 2GB RAM, with a 500GB Lacie external harddrive hooked up to it (SAMSUNG HD502IJ Media). I'm trying to make a ~30GB partition in FAT32 so that I can back up my PS3 harddrive on it. However, in Disk Utility, when I click the dropdown under partition for "Format", FAT32 or MS-DOS doesn't show up. I only see both Mac OS formats, ExFAT, and Free Space. Has anyone else had this problem? Is there anything I can do without completely wiping this drive? I have a ton of files on here and nowhere else to store them temporarily. Thanks!
