NTFS/GPT Mount exited with Exit Code 13

Question

This is a duplicated post since I didn't get any help on askubuntu.com.

I have a 1TB external hard drive that I recently formatted to NTFS. It was mounting on my Ubuntu 11.10 fine until just now. I didn't make any changes to affect my OS or my exhdd.

The error that I get is:

Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 0).
Failed to mount '/dev/sdb2': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

I did read this and this. But neither helped.

I tried installing ntfsfix but no such package exists anymore. I have never used this HDD on a windows machine. If I need to use an other machine to do stuff to fix this, I have access to a mac.

Any advice?

This is my sudo fdisk -l output: What in the world is GPT? I didn't do that. It used to be NTFS.

Answer 1

This is the thing that worked:

1. I first needed to get ntfs-3g (sudo apt-get install ntfs-3g)
2. Run sudo fdisk -l to figure out where the mount point is. Mine was /dev/sdb1
3. I ran ntfsfix -b /dev/sdb1 and that fixed the problem.

Answer 2

Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sda1': Input/output error

Solution :-

1. sudo fdisk -l

2. sudo ntfsfix /dev/select_disk_name

3. To find Disk name:
   Go dashboard -> Disk utility -> Click disk -> then show Device /Dev/***
