Ubuntu – Fix corrupt NTFS partition without Windows

fsckhard driventfspartitioning

MY NTFS Partition has gotten corrupt somehow (it's a relic from the days when I had Windows installed).

I'm putting the debug output of fdisk and blkid here.

At the same time, any OS is unable to mount my root partition, which is located next to my NTFS partition. I'm not sure if this has anything to do with it, though. I get the following error while trying to mount my root partition (sda5)

mount: wrong fs type, bad option, bad superblock on /dev/sda5,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

When I open gparted (using live CD), I get an exclamation next to my NTFS drive which states GParted Screenshot showing error

Is there a way to run chkdsk without using windows ?

My attempt to run fsck results in the following :

ubuntu@ubuntu:~$ sudo fsck /dev/sda
fsck from util-linux-ng 2.17.2
e2fsck 1.41.14 (22-Dec-2010)
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

Update: I was able to fix the NTFS partition running chkdsk off Hiren's BootCD, but it seems that the superblock problem still remains.

Update 2: Fixed superblock issue using e2fsck -c /dev/sda5

  • Install ntfs-3g with sudo apt-get install ntfs-3g. Then run the ntfsfix command on your NTFS partition.

    For example:

    ntfsfix /dev/hda6

    ntfsfix v2.0.0 (libntfs 10:0:0)

    Usage: ntfsfix [options] device

    Attempt to fix an NTFS partition.
    
    -h, --help             Display this help
    -V, --version          Display version information
    

    Developers' email address:

    linux-ntfs-dev@lists.sf.net Linux NTFS homepage: http://www.linux-ntfs.org


    For newer Ubuntus You can use -b and -d option together. -b tries to fix bad clusters and -d to fix dirty states. So the command can be

    sudo ntfsfix -b -d /dev/sda6
    

    --help shows them

    ntfsfix v2015.3.14AR.1 (libntfs-3g)
    
    Usage: ntfsfix [options] device
        Attempt to fix an NTFS partition.
    
        -b, --clear-bad-sectors Clear the bad sector list
        -d, --clear-dirty       Clear the volume dirty flag
