Topic: [SOLVED] Current NTFS Volume Size is bigger than the device size

Hi!
I used 0.5.2.9 GParted live to resize a NTFS partition from 120gb to 200gb.

Now ntfsresize show me this message :

ntfsresize v2.0.0 (libntfs 10:0:0)
Device name  : /dev/sda3
NTFS volume version: 3.1

Current device size: 210591843840 bytes (210592 MB)
ERROR: Current NTFS volume size is bigger than the device size!
Corrupt partition table or incorrect device partitioning?

Re: [SOLVED] Current NTFS Volume Size is bigger than the device size

From the output from fdisk and parted, it appears that your first NTFS partition begins at sector 2048, and not at sector 63.  Thus to capture the NTFS PBR you will need the following command:

NOTE:  Be extra careful to type this command in properly, otherwise loss of data could result.

dd if=/dev/sda of=sda1-skin81.pbr bs=512 count=1 skip=2048

where sda1-skin81.pbr is the name of the file that will need to be uploaded.

Re: [SOLVED] Current NTFS Volume Size is bigger than the device size

Based on the sda1-skin81.pbr file, it appears that the /dev/sda1 partition is okay.

Now that I reread your first post, I see that the problem arises with the /dev/sda3 partition.

Please use the following command to capture the NTFS PBR for the /dev/sda3 partition:

NOTE:  Be extra careful to type this command in properly, otherwise loss of data could result.

dd if=/dev/sda of=sda3-skin81.pbr bs=512 count=1 skip=123700500

where sda3-skin81.pbr is the name of the file that will need to be uploaded.

Ops! You are right, sorry!

Re: [SOLVED] Current NTFS Volume Size is bigger than the device size

Since you were trying to shrink the partition, we will decrease the NTFS volume size to fit within the partition.

The change I have made to the file is from a length of 756,609,696 sectors:
00000020   00 00 00 00  80 00 80 00  E0 46 A2 2D  00 00 00 00
To a new length of 411,321,194 sectors:
00000020   00 00 00 00  80 00 80 00  42 20 84 18  00 00 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 NTFS PBR: sda3-skin81_new.pbr

2) Load the new NTFS PBR on your hard disk.
NOTE:  Be extra careful when entering the commands.  Data loss could result otherwise.

dd if=sda3-skin81_new.pbr of=/dev/sda bs=512 count=1 seek=123700500

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.

Thank you so much gedakc ! It worked.
