ntfsck?

It is even in F9.

A brief look at the source suggests ntfsck takes a single argument,
the device partition that contains the filesystem to be checked.
Example:

  ntfsck /dev/sdb1

What does it actually do?  That might require a deeper look at the code.

The program does not appear to exercise much discretion if asked to
examine a partition that is not an NT filesystem.  I inadvertently asked
it to look at a FAT partition and it complained:

  Boot sector: Bad jump.
  Boot sector: Bad NTFS magic.
  First attribute must be after the header (0).

then appeared to loop.
