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

Thank you Manuel for posting this problem in a new thread.  I have deleted the entry from the previous thread.  Now on to fixing the problem smile

I will need both the Master Boot Record, and the NTFS Partition Boot Record to investigate this problem.


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-manuel.mbr bs=512 count=1

where sda-manuel.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-manuel.pbr bs=512 count=1 skip=337365

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


Upload these files to a media sharing site, such as mediafire, and post the link to these files in this forum post.

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

From these two files I can see the following:

165,485,565 sectors - length of partition in MBR
312,239,328 sectors - size of NTFS file system from NTFS PBR

To fix this problem I think it is safest to change the partition size to encompass the whole NTFS file system.
The change I have made to the file is from a length of 165,485,565 sectors:
000001D0   01 15 07 FE  FF FF D5 25  05 00 FD 1B  DD 09 00 00
To a new length of 312,239,329 sectors:
000001D0   01 15 07 FE  FF FF D5 25  05 00 E1 64  9C 12 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-manuel_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-manuel_new.mbr of=/dev/sda bs=512 count=1

3) Reboot the computer

4) 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:
WARNING! Problem Resizing File Systems with GParted

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

for me it's urgent, I try to change it...
I hope to do it right!


P.S.: I saw your reply and I see my file seems to be ok
one day to understand what you have done in less then 5 minutes!

P.P.S.: It seems to run correctly, it has to finish the second chkdsk, but I think there're no problems!

THANK YOU!
