Turns out the PS3's HDD stores a copy of the NAND/NOR by default and they use what i'll deem "confuser FAT" (in both FAT16 and FAT32 flavors) as partitions as they're FAT* partitions with nonsensical/zeroed header bits, which make tools cry ("the first FAT32 partition says the drive has 354 heads, the second partition says 0 and the drive says it has 2...?" "The drive is 320GB, so why in the hell is the partition table reporting a sensical size but the FAT has an entry 2TB thataways?" "This FAT16 filesystem has filenames stored as 16.2 instead of 8.3 natively???")
