The GUI also does not allow you to defrag individual Volumes, perform an analysis, or provide any useful reporting. Ironically no defrag information can be found in Vista event logs or Performance and Reliability tool. Fortunately, running disk defragmenter from the command prompt you will need Admin rights , gives you greater control of which volume or volumes to defrag, allows you to run analysis and view detailed reports.

To view disk defragmenter available command line options, open a command prompt and enter the following command:. Attempts to consolidate only fragments smaller than 64MB. Attempts to consolidate all file fragments, regardless of their size. The defragmentation and analysis output is more detailed.

An example output, shown below, runs analysis on the C: drive with verbose mode:. As you can see, a more detailed analysis is shown with information at the bottom indicating that the volume is not fragmented. A similar report will be displayed after fragmenting a volume.

How come it says I need administrative permissions even though I'm using an administrator user. I need help.

Time does not necessarily double. It does not really tell you how well the fragmentation process went but as you could see from the visuals above, it is quite effective. The "-r" option tells the defragmentation utility to treat files that are fragmented with 64 MB fragments or larger as though they are not fragmented.

This partial defragmentation is the default for "defrag", and it's the only way the GUI defragmenter in Vista works. You can also force the defragmenter to defragment everything. That is, even if the file fragments are larger than 64MB, the Vista defragmenter will still attempt to put the file into contiguous sectors. To do this, run the defragger with the following options:.

As you have probably have guessed, "-w" tells the Vista defrag tool to do a full defragmentation. All file fragments will be consolidated where possible. You will still not get any feedback as to the progress of the defragmentation with the command line tool, just as you did not with the GUI version.

However, at the beginning and the end of the defragmentation, "defrag" with the "-v" option will give a report, much like the old Windows XP GUI defragmentation utility.

Again, though, it will not report fragmented files with 64 MB fragments or larger as being fragmented. With the command line version of the Windows Vista defragmentation utility, you have at least a modicum of control over the defragger, and some information about your hard disk file fragmentation.
