Gparted partition resize gone wrong - failed to read last sector

I have tried to resize (shrink) my NTFS partition so that I will be able to get more space for my ext4 Ubuntu's (12.04 64 bit) partition but after the partition has been resized I am unable to mount it. I used Gparted to do this.

I assume there is a problem somewhere with the partition table but I do not know where and how to fix it.

This is what I get in Gparted information window on NTFS partition:

fdisk -l and mount /dev/sda5 /media/d

root@UBUNTU:/home/XXX# mount /dev/sda5 /media/d
Failed to read last sector (718198764): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda5': Invalid argument
The device '/dev/sda5' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Partition table entries are not in disk order

Solution 1:

After few minutes of digging I have found this guide which uses ntfs-3g package to recover broken ntfs partition.

Great tool! I can recommend it to everyone.

Solution 2:

This did the job for me:

sudo ntfsfix /dev/sda1

Where sda1 is the NTFS partition with the issue.

After that command and next restart into windows, it will check the disk and things will work fine again.
