It prints warning, but lets you mount it. I sometimes mount broken fs's rw; it actually saved me once when I was hitting fsck bug. It is also handy when quickly recovering scratch machine. MS-DOS had no fsck... and survive. ext2 can survive with similar results if you just dont fsck... > I think nobody really wants to read reports where Linux has shreddered a > filesystem, do we?
