[Defrag stops after a brief operation.]

I checked and defragged the machine using command line tools and defraggler only starts and stops into the process.

Any other ideas?

Are you referring to Defraggler?

Some defrag issues such as failure to defrag, freezing, etc., (regardless of the defrag software) may be remedied by running the disk error checker ChkDsk on the hard disk(s).

It is a brand new computer and the computer and health is excellent.

I have using defrag for many years now, never had a problem. I have a ACER Aspire with latest WIN 10.

Now for this version the sectors are grey and after a few moments it crashed.

Please inform me on how to fix the problem.
