If its fails stop here and try to back up the data on the disk by connecting it as a second drive to another computer. Run the manufactures diagnostics on the disk to prove it has failed. If not reformat it with option to map out bad spots and repeat above steps. Otherwise buy a new disk and partition and format it.

- From the My Defrag disk map check if the Page File is fragmented delete it and run Defrag (step 2) again. Otherwise go step 5. You can locate the Page File(s) in the map by placing the gun sight cursor over the red (unmovable) elements.
- Recreate (Custom) Page File with Initial Size = Maximum Page Size = 1.5 * total RAM. Note this recommendation is for typical desktop systems. For others please scan the web for the best value for you.

- Optionally uninstall My Defrag
