That's not surprising. msdosfs doesn't check very good against ``can't happen'' situations. But i think you could always damage any kind of filesystem on a disk into a state where the kernel might panic later. That's why you're normally supposed to fsck the file system before, but we currently don't supply a msdosfsck program. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
