It often happens that the file data is written before the file system data is written. Ie you'd first write down the files, then the data describing where to find the files. And without the later there is no chance to find the data. Especially file systems with an prehistoric structure like FAT are really prone to such problems. ext2/3, zfs, btrfs less so because of certain guarantees they give on data/metadata consistency. > It seems odd to me that even if there was some kind of error that the > drive would be so *completely* empty. There is probably a chance that you still have some data left, but it's not referenced by the file system.
