=== Unable to mount ntfs3 with dirty volume ===

When attempting to mount an <code>NTFS</code> partition using the <code>ntfs3</code> filesystem driver via the {{nixos:package|ntfs3g}} package, the mount operation may fail:

# mount /dev/sda1 /mnt -t ntfs3

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.

dmesg(1) may have more information after failed mount system call.

</syntaxhighlight>

With the resulting dmesg output:

# dmesg

...

[168659.819978] ntfs3: sda1: It is recommened to use chkdsk.

[168659.820833] ntfs3: sda1: volume is dirty and "force" flag is not set!

</syntaxhighlight>

This indicates that the NTFS volume has the “dirty” flag set. In this state, the <code>ntfs3</code> driver refuses to mount the filesystem.

To clear the dirty flag, run <code>ntfsfix</code> on the affected partition:

# ntfsfix --clear-dirty /dev/sda1

</syntaxhighlight>

If <code>ntfsfix</code> fails with an error <code>Windows is hibernated, refused to mount</code>, the partition can be mounted using <code>ntfs-3g</code> with the hibernation file removed:

# ntfs-3g -o remove_hiberfile /dev/sda1 /mnt

</syntaxhighlight>
