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

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

    Attempt to fix an NTFS partition.

    -b, --clear-bad-sectors Clear the bad sector list
    -d, --clear-dirty       Clear the volume dirty flag
    -h, --help              Display this help
    -n, --no-action         Do not write anything

I've just fixed my USB drive using "testdisk", a Linux command line (yet friendly) utility. My drive was not even mounting in Windows and Windows 8 discovered like 6 partitions (when the drive had only one).

To use the utility, install it:

sudo apt-get install testdisk

Then run it:

sudo testdisk

and follow the instructions. You must search for partitions and then write the changes.

Hope this help anyone.

Just to clear some of your points up.

My attempt to run fsck results in the following :

ubuntu@ubuntu:~$ sudo fsck /dev/sda

...

fsck.ext2: Bad magic number in super-block while trying to open /dev/sda

Now, thats not wonder, because you are trying to fsck the disk, and not its partition. What fsck does is, it tries to recognize the FS type. Because you have given it raw disk surface, it fails to recognize and resorts to default type - ext, calling fsck.ext.

fsck.ext does not find any FS signature in the location and tries to find superblocks. Ultimately it fails, because its disk with only NTFS partition type.

This is why you have this error.

The correct command would be:

sudo fsck /dev/sda1

That would feed the FIRST partition of first sata hard drive, not the first sata disk itself.

In Ubuntu 14.04 Just try this

sudo ntfsfix /dev/sdXY

Where XY is your partition. (/dev/sda2 in your case)
