Usage: mkfs.ext3 [-c|-l filename] [-b block-size] [-C cluster-size]

[-i bytes-per-inode] [-I inode-size] [-J journal-options] [-G flex-group-size] [-N number-of-inodes] [-m reserved-blocks-percentage] [-o creator-os] [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory] [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]] [-t fs-type] [-T usage-type ] [-U UUID] [-jnqvDFKSV] device [blocks-count]

Cek Bad Blocks

WARNING: Proses ini akan memakan waktu lama sekali. Mungkin semalam-an

Memformat sambil cek bed blocks

mkfs -L data -c /dev/sdb1

Menggunakan badblocks

WARNING: Proses ini akan memakan waktu lama sekali. Mungkin semalam-an

Sebelum mkfs kita dapat menjalankan badblocks

badblocks -wsv /dev/<drive>
[...]
done
Pass completed, 527405 bad blocks found. (0/0/527405 errors)

Atau output di simpan ke sebuah file

badblocks -wsv -o /root/<badblocks.txt> /dev/<device>
Checking for bad blocks in read-write mode
From block 0 to 488386583
Testing with pattern 0xaa: done
Reading and comparing:   6.36% done, 0:51 elapsed. (0/0/14713 errors)
[...]
Testing with pattern 0x00: done
Reading and comparing: done
Pass completed, 527405 bad blocks found. (0/0/527405 errors)

file tersebut digunakan saat format

# mkfs.<filesystem-type> -l /root/<badblocks.txt> /dev/<device>

Catatan: Note: 0/0/527405 errors adalah <number of read errors>/<number of write errors>/<number of corruption errors>.
