Cannot do disk defrag
Top disk defrag headaches are that it gets stuck at ten per cent complete, or it endlessly restarts. Defrag initially scans the disk for errors and this accounts for the first four per cent of the progress.
Between five and nine per cent, Defrag devises a plan of action. Neither process should take too long. From ten per cent onwards, Defrag moves data. This is slow, but the gauge should creep up gradually. Defrag can die in action, but it can appear to freeze if it seriously underestimates how long part of the disk will take to
complete.
If Defrag stops halfway, you should listen for knocking or winding noise that may be coming out from the hard drive. This is an indication that the hard drive may be giving way. Backup your data, and if there is nothing important on the hard drive, try leaving it running overnight.
Continual restarting is normally due to another piece of software cutting in and changing something on the
disk. Because Defrag’s plan might now be inappropriate and lead to damage, it starts over.
Tracing the culprit may be difficult because too many background programs are quietly ticking away. If disabling your screen saver and any scheduling programs doesn’t work, just reboot to Safe Mode
and run Defrag from there.
The more recent cause for this issue is spyware that likes to stay in the background and poll their servers thus causing disk writes and restarting defrag.
