Your disk is taking longer to handle the error than we allow it to. Your best bet at this point is probably to mount the partition forced readonly (mount -f -o ro), copy everything meaningful off the the partition, then dd zeroes over it to give the drive a chance to remap the sector(s) in question. > > last night all of a sudden my box halted, without panicing or > rebooting. > After pressing the reset-key, it came back up, and didn't manage > to finish fscking a partition on an IDE-disk of mine.
