Hard drive does not complete defragmentation

When the hard disk is sorted, it is always restarted at a certain point, repeated so that it cannot be completed successfully.

When the hard disk is defragmented, if you write the hard drive or the background program has a startup program, you'll start over again. Before defragmenting the disk, the screen saver is turned off, and the options for the system to wait for and turn off the hard disk are modified to never. Check the system background to see if there are other programs running and shutting them all down. If connected to the LAN, it is best to unplug the network cable. This completes the hard drive to defragment the piece smoothly.
