Topic: [SOLVED] Current NTFS volume size is bigger than the device size!!!!

Please help. I cannot boot into my /dev/sda2 (win7 ntfs) partition. This occurred when I attempted to shrink sda2 to create a new partition.

1)  Which partition is experiencing the error?
* /dev/sda2
2)  Which version of GParted or Live CD you used?
* Gparted 0.5.1 from Knoppix Live CD
3)  The output from the following two commands:
root@Microknoppix:~# fdisk -l -u

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors

Re: [SOLVED] Current NTFS volume size is bigger than the device size!!!!

Next we will need copies of the Master Boot Record and the NTFS Partition Boot Record.

You can capture the Master Boot Record in a file with the following command:

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

dd if=/dev/sda of=sda-silv3r.mbr bs=512 count=1

where sda-silv3r.mbr is the name of the file that will need to be uploaded.


You can capture the NTFS Partition Boot Record in a file with the following command:

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

dd if=/dev/sda of=sda2-silv3r.pbr bs=512 count=1 skip=206848

where sda2-silv3r.pbr is the name of the file that will need to be uploaded.


Then upload these files to a media sharing site, such as mediafire or filefactory, and post the link to these files in this forum post.

Re: [SOLVED] Current NTFS volume size is bigger than the device size!!!!

one more info that you might find useful. When I do a "check" for /dev/sda1 in gparted it's ok. But when I try to do it in /dev/sda2 it show's this error.
The exclamation point symbol is only shown in /dev/sda2.

Corrupt partition table or incorrect device partitioning?

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 976,564,216 sectors:
00000020   00 00 00 00  80 00 80 00  F8 2F 35 3A  00 00 00 00
To a new length of 894,645,781 sectors:
00000020   00 00 00 00  80 00 80 00  15 36 53 35  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: sda2-silv3r_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=sda2-silv3r_new.pbr of=/dev/sda bs=512 count=1 seek=206848

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.

For future partition editing (and to avoid the problem you encountered), we highly recommend a newer version of GParted such as that contained on the most recent GParted Live image (0.8.0-5).
