Topic: [Solved] Windows 8.1 NTFS partition is unreadable by GP Live 0.25.0-3

In  a multi-boot computer my Windows 8.1 NTFS partition is seen as unreadable by GParted. I boot into this partition as my Windows 8.1 c: drive and I have run a chkdsk on this partition in Windows 8.1 with no errors found. But Gparted Live shows the partition with one of those problem triangles next to it and when I view the partition property the message tells me that the data in the partition is unreadable. The partition is identified as a NTFS by the Partition Editor in the GParted live startup.

Is there any way I can determine why Gparted Live considers the partition unreadable despite the fact that I am actively using it as my main partition when I run Windows 8.1 ?

Did you properly shut down Windows (Start -> Shutdown) before booting into GParted?

Also be sure the Windows installation is using basic disk partitioning and not Windows proprietary Dynamic disk partitioning.

Windows was properly shut down and basic disk partitioning is being used.

You said you got this message against the NTFS "C:" partition, but nothing else:

Unable to read the contents of this file system!
Because of this some operations may be unavailable.

As there are no errors reported in the partition messages, you'll have to run some commands and post the results so we can see what is happening.  (Making lots of assumptions about your disk layout, so you may need to change the /dev/sda and /dev/sda2 device names to match your actual disk layout shown in GParted).  Run the following commands in a terminal:

sudo su -
parted /dev/sda print
ntfsresize --info --force --no-progress-bar /dev/sda2

The message I get when I look at the Information in GParted for the partition in question is:

The cause might be a missing software package.
The following list of software packages is required for ntfs file system support:  ntfs-3g / ntfsprogs.

The result from:

parted /dev/sda/print

is:

Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/512B

The partition in question is /dev/sda4. The result of:

ERROR: NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.

I go into Windows 8.1, run chkdsk c: /f, am told that it will be rescheduled the next time I boot. I reboot Windows 8.1, it checks the c: partition and finds no errors. I reboot Windows 8.1. I then reboot into GParted Live and it gives me the same errors for the ntfsresize it gave originally.

So the ntfsresize says there is something wrong with the partition but Windows 8.1 says that the partition has no problems or errors.

If Windows is fine with the partition, but even after running "chkdsk c: /f" and rebooting and shutting down properly, you still find that ntfsresize is reporting an error, then you might have found a bug in the ntfsresize command.

ntfsresize is part of ntfs-3g.  You might consider raising the issue with the ntfs-3g team.

After running

chkdsk c: /f /r

, which caused a full fix and repair of my Windows 8.1 boot drive when I rebooted Windows 8.1, GParted Live now shows the partition without any error. Evidently just running

chkdsk c: /f

was not good enough in my case.
