But note that different filesystems can handle bad sectors differently, read-only filesystems is the most common default though. In 'man 8 mount' the option "errors=" describes the different values for ext2/3/4. Configuring it to "continue" will most likely cause data corruption or other bad problems and is definitely not advised ;-) Niels
