ntfsfix error: Volume is corrupt. You should run chkdsk. After ntfsresize
You need to boot into Windows, or use a different computer with Windows if it's an external drive. Windows should automatically detect that there's an issue and have a pop-up asking if you would like to check the disk for errors, so just press yes and you should be good.
If you're planning on using the drive on Linux more than Windows, I strongly suggest that you use ext4, as it works much better than NTFS in Linux, as I have learned the hard way.
BTW, according to the manpages:
ntfsfix is NOT a Linux version of chkdsk. It only repairs some fundamental NTFS inconsistencies, resets the NTFS journal file and schedules an NTFS consistency check for the first boot into Windows.
