Error resizing ntfs partition with gparted

Not only with ntfs but also with ext3 and ext 4 ther seem to be probelms when resizing your partiton. Always backup you data.
The error you get is:

ERROR: Current NTFS volume size is bigger than the device size!

When you go to the parted forum you will be very well guided to solve the problem though.
And so this didn't lead to data loss for me.
Just stay cool and don't start deleting partitions in your panic.
