Solved CMD defrag has stopped working

[outlawed]

Everything was working fine last night, and I haven't made any changes to my system whatsoever and now when I booted up this morning my cmd line defrag doesn't want to work anymore.

Disk defragmenter via system tools still works, it's just the cmd line part doesn't want to work anymore.

Any ideas on what could be causing this?

Take a look here. Defrag
It appears the command is written wrong from examples shown.

You may want to bookmark the below page. Reference for all CMD's.
http://windows.microsoft.com/en-US/windows7/Command-Reference-Overview

To defragment the volume on drive C while providing progress and verbose output, type: defrag C: /U /V

To defragment the volumes on drives C and D in parallel in the background, type: defrag C: D: /M

To perform a fragmentation analysis of a volume mounted on drive C and provide progress, type: defrag C: mountpoint /A /U

To defragment all volumes with normal priority and provide verbose output, type: Defrag /C /H /V

The command is correct, as it's the same command I have been using.

The /c parameter invokes on ALL volumes.

The command I use is even used as an example when defrag /? is done:

Examples:

defrag C: /U /V
defrag C: D: /M
defrag C:\mountpoint /A /U
defrag /C /H /V

Hi there,

Here is article that explains it. http://www.sevenforums.com/tutorials/11733-disk-defragmenter-open-use.html

If that fails then run http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

Thanks for the link, however I know how to do defrag via command prompt as I've been doing it for as long as Microsoft has been allowing it.

I did a defrag via cmd last night with the "defrag /c /h /v" line and everything worked perfectly, just that it stopped working when I booted this morning.

Will give the sfc /scannow a go and post results when it finishes.

UPDATE: sfc /scannow has finished and found nothing wrong:

Windows Resource Protection did not find any integrity violations.

Hi there,

After SFC I assume you rebooted and tested it. Enable Build-in administrator http://www.sevenforums.com/tutorials/507-built-administrator-account-enable-disable.html and test it in that account and see if it works. Maybe it's something up with User profile.

Okay, same as I see.

I tried this with Win 7 Ultimate running under Oracle Virtual box and it would not run. Said insufficient permissions.

I then opened an Elevated Command Prompt (right click on Command Prompt and select Run as Administrator) and it ran correctly. Try that, see if it helps.
