I have a Viking Interworks 128 MB compact flash card. My Mac tells me (via Disk Utility) that it's in MS-DOS format. No idea if that means FAT or FAT 32, however. There is no option to reformat specifically to FAT in Disk Utility.
So, should I try to hook up my card reader to a PC via USB and reformat? I'm not sure how to do it, but I suppose I can figure it out.
My hunch is that this card is in FAT format already. It's an old card. And it's small (128 MB). I was under the impression that only newer, larger cards were FAT32.
Is my other option to go out and buy a new card?
