In this situation I think it is safest if we increase the partition size to encompass the entire NTFS volume.
The change I have made to the file is from a length of 51,263,352 sectors:
000001C0 01 00 07 FE FF FF 3F 00 00 00 78 37 0E 03 00 00
To a new length of 78,140,089 sectors:
000001C0 01 00 07 FE FF FF 3F 00 00 00 B9 52 A8 04 00 00
Note: The NTFS volume size is always 1 sector less than the total number of sectors in the partition table entry because the NTFS backup sector is not considered part of the NTFS volume.
To apply this change:
1) Download the new MBR: sda-stasxh_new.mbr
2) Load the new MBR on your hard disk.
NOTE: Be extra careful when entering the commands. Data loss could result otherwise.
dd if=sda-stasxh_new.mbr of=/dev/sda bs=512 count=1
3) Reboot the computer
4) Check that the file system is recognized in GParted
5) If all seems fine then I would advise booting into Windows and running "chkdsk /f /r" multiple times, until there are no more faults.
NOTE: We are tracking a problem with GParted resizing file systems. See post:
