Defragmentation aimless?
It defrag the disk, and in a moment the next and subsequent fragments and each time the defragmentation takes hours, days (depending on the number of fragments and the size of the files). What to do to ensure that the fragments do not appear, is there any intelligent record that eliminates real-time I / O fragments?
Defragmentation is an important thing only in the case of data recovery, in the speed - it is better not to run the defragmenter because the disk mechanics' wear will be higher and the disk life will be shorter.
