Analysing your volumes

Analysing your hard disks gives you an overview of how heavily fragmented they are. O&O Defrag creates a detailed status report about the fragmentation level once the analysis has been completed.

This level will be somewhere between 0 and 100 – the lower the number (zero is the ideal), the less fragmented your hard disk. A value near 100 is the worst case – your files are almost completely fragmented. Even values of around 30 mean that the performance of your system is seriously suffering from the level of fragmentation, and that a defragmentation run is strongly recommended.

 

Level

Explanation and action needed

< 10

All files are almost completely defragmented. This is the ideal condition and can only be achieved and maintained through regular defragmentation.

10 – 30

This level is reasonable, and means that your hard disks are in good condition.

31 – 50

Your system is working more slowly than normal because of heavy fragmentation. Defragment regularly and use the time planning facility included in O&O Defrag. This will keep your system running at a good speed.

51 – 90

Your system is very heavily fragmented and is suffering from very serious performance losses. You should defragment your system right away and create jobs for regular defragmentation. Compare the fragmentation levels before and after the defragmentation run.

> 90

Almost all of your files are fragmented – you’ve probably never, or very seldom, defragmented your system. The effect on your system is dramatic. Defragment your hard disks frequently, and bear in mind that it might take several runs before an ideal fragmentation level is reached.

 

Start analysis

•

Select the volume to be analysed in the volume list.

•

Start the analysis via the toolbar or from the context menu (select ôAnalyseö). The analysis can take a few moments, even if the volume is small. You can follow the progress of the analysis on the volume symbol and the progress display.

•

When the analysis is finished, a dialog window with a summary of the volume information will be displayed. You can display the detailed status report as a HTML document in your web browser.

•

Note: You can analyse several volumes simultaneously. Mark the various volumes by keeping the Ctrl key depressed whilst selecting.
