Verificar bloques (clusters) malos en un disco duro Linux (ext4)
Verify bad blocks hard disk Linux (ext4) Opción 1 (Durante el formateo): $ mkfs.ext4 -c /dev/sda1 Opción 2 (En cualquier momento, después del formateo): $ umount /dev/sda1 $ fsck.ext4 -cDfty -C 0 /dev/sda1 Run a ext4 file system check and badblocks scan with progress info Nothing fancy, just a regular filesystem scan that calls the badblocks program and shows some progress info. The used options are: -c ? check for bad sectors with badblocks program -D ? optimize directories if possible -f ? force check, even if filesystem seems clean -t ? print timing stats (use -tt for more) -y ? assume answer ?yes? to all questions -C 0 ? print progress info to stdout /dev/sdxx ? the partition to check, (e.g. /dev/sda1 for first partition on first hard disk) NOTE: Never run fsck on a mounted partition!
