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

Seems to be the same problem as others, a bit of a newbie so apologies in advance.

I was trying to reduce my 150gb drive with XP to 100 and create a new 50gb ntfs primary partition.

I'm having problems with sda1, saved the error message on mediafire (see link at bottom).
I used the latest version of GParted (0.5.0-3), downloaded on 12-dec-2009.

Let me know if there is anything else I can provide to help as I'd love to get my computer back.

Thanks in advance for any help!

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 312,576,632 sectors:
00000020   00 00 00 00  80 00 80 00  78 8A A1 12  00 00 00 00
To a new length of 207,543,671 sectors:
00000020   00 00 00 00  80 00 80 00  77 DD 5E 0C  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: sda1-michio_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=sda1-michio_new.pbr of=/dev/sda bs=512 count=1 seek=63

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.

Thanks!!! Still got a yellow error box in GParted (complained about sectors not matching up), but seems to started up again fine and chkdsk /f /r ran smoothly, so willing to call it solved.  Thanks again, especially for the quick turnaround!

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

The "chkdsk /f /r" should hopefully have taken care of the yellow error box shown in GParted.

I am glad to hear that the problem is now solved.  smile

And thanks for marking the initial post as solved.
