I'm equally perturbed at the wording used in Diskeeper, as the statement on
its Reliability tab says:

Critical!

The computer's reliability is severely affected on volume D:

The reliability level is at "Critical" for the following reason:

The MFT usage is currently 96 percent of the total MFT size, which
indicates it is likely the MFT will become fragmented.

What worries me about this statement is that it is so easy to misunderstand
what is being said. There is no problem with that figure of 96 per cent
(which may differ from system to system, of course) - indeed, I would take
no issue if it said 100 per cent - but problems really can arise if the
Master File Table (MFT) becomes seriously fragmented. The MFT is a file
that contains an entry for each of the other files stored on your hard
disk. Since it is important that the MTF does not become fragmented,
one-eighth of your hard disk space is allocated as 'Reserved System Space'
for it to grow into. As files are added to the system, so the size of the
MFT grows. However, this does not pose a problem for a while, because it
can simply expand into its own contiguous disk area.
