I've been searching for awhile but I haven't been able to find anyone with any solutions or anyone with my exact problem. Sorry if I missed anything and am reposting an existing issue. So my exact problem is that I usually use my Flash between my Mac and other PCs. And I just installed OSX Snow Leopard from my 8GB Kingston Flash. Now I know to use Disk Utility to reformat to MS-DOS (FAT) to be able to to use it between the to OSs again. So I do that but PCs won't read it and ask me to reformat it again. I'd happily do that cuz I know as long as it's in FAT or FAT32 the two OSs will be able to read and write from each other. But the PC only recognizes 200 mb and when I do reformat it on the PC there are now 2 different Partitions. One being the PC's 200 mb in FAT and the other Mac's almost 8GB MS-DOS. I've tried a few different things too. I've tried Partitioning the whole thing over again int MS-DOS after having erased everything. Which I see only causes the Flash drive to shrink from 8.01 GB to 7.80GB and still isn't readable by a PC. Then I tried Erasing it to free space but PCs still don't recognize it and still ask me to reformat the 200mb is sees on the Flash. Please if anyone can help it would be Greatly Appreciated! Thanks much to anyone who can help me.
