SOLUTION:

Disk fragments are tiny unused storage areas scattered on the disk. The system cannot directly reutilize these ''blank'' spaces and system performance can decrease as system operations usually cause the number of unused storage gaps to increase. To defragment your disk storage, do as the following:

1.Go to the Tools tab from disk Properties and select Defragment Now.

2.Select the time and scheme to be used by the defragging program, then start the defragmenting program.

Defragmentation usually takes a long time.
