Topic: [SOLVED] NTFS resize problem

Hello.

I'm not sure how to do some steps from the tutorial, so I decided to open this thread.

Here it goes:

fdisk -l -u

Re: [SOLVED] NTFS resize problem

What is the problem you are experiencing?

Which partition is involved?

What steps led you to the problem?

Re: [SOLVED] NTFS resize problem

Resized partition sda2 (wich contains win7) to get space for a linux system (sda3). Resize failed, got the NTFS size problem.

ext4 is ok, but can't mount sda2.

Re: [SOLVED] NTFS resize problem

By "got the NTFS size problem" do you mean that you have seen the message "ERROR: Current NTFS volume size is bigger than the device size!"?

If so, then 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-jlopezinc.mbr bs=512 count=1

where sda-jlopezinc.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-jlopezinc.pbr bs=512 count=1 skip=206848

where sda2-jlopezinc.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, and post the link to these files in this forum post.

Re: [SOLVED] NTFS resize problem

Yes, exactly. The "ERROR: Current NTFS volume size is bigger than the device size!" message.

Here it is:

PBR

Thank you.

Re: [SOLVED] NTFS resize problem

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 156,092,415 sectors:
00000020   00 00 00 00  80 00 80 00  FF C7 4D 09  00 00 00 00
To a new length of 114,687,999 sectors:
00000020   00 00 00 00  80 00 80 00  FF FF D5 06  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-jlopezinc_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-jlopezinc_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.

Re: [SOLVED] NTFS resize problem

Ok, that worked fine.

For the record, the OS Win7 that is on sda2 partition could boot right after I made the change. Then, I could fix the errors.

Thank you.
