The next things to do will be, in order... 


Invest in a backup strategy; Time Machine, Backblaze etc &amp; use it.
Throw that drive out &amp; use an HFS+ formatted drive, with Journalling - because Mac's support for NTFS is not great.. &amp; by default can't write or repair NTFS, so you either have Paragon or similar or you enabled it via Terminal.
