NTFS The disk contains an unclean file system

When trying to mount a Windows NTFS partition on Linux, I got the following error message

root@vmi552968:~# mount -t ntfs /dev/sda1 /mnt
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
Could not mount read-write, trying read-only
root@vmi552968:~#

This is because Windows Machine is not properly shutdown. If you don’t have access to properly shutdown, for example, you lost password for windows, you can use the “ntfsfix” command to fix the warning.

ntfsfix /dev/sda1

Example

root@vmi552968:~# ntfsfix /dev/sda1
Mounting volume... The disk contains an unclean file system (0, 0).
