Hello Oagheru, Do you still need help with this issue?

I cannot comment on the NOD problem but the following may help you with your Diskeeper error.

Diskeeper will not defragment a drive if it is in a "dirty" condition. Diskeeper does this since the integrity of the data on your drive is a primary concern and Diskeeper will not defragment a drive that is not reporting back as fine.

I would suggest that you run the following command to make sure your drive is not in a dirty state and to fix any possible errors:

chkdsk c: /f

This assumes that your drive is drive c:. If you have other hard drives on this system, please replace the c: with the appropriate drive (ex. d:, e:, etc.)

Once this is done, Diskeeper should be able to work again.
