FAT32 filesystems are supposed to maintain an alternative file allocation table, but I can't find any way of actually using it. See http://en.wikipedia.org/wiki/File_Allocation_Table#Design for more details. It may well be that the data at the start of the FAT32 partition is toast, so Linux won't even try mounting it. Alternatively, it may well be that Linux *has* already tried using it, but it's also toast. (FAT32 keeps its file allocation tables together, where they're more susceptible to disk problems. ext2 keeps them scattered through this disk.)
