What if the hard drive doesn't finish the defragmentation?
Workaround One:
Defragment the hard disk in the system, and start again if a write hard drive and some background programs start. Before defragmenting the hard disk, disable the screen saver, set the system to wait, turn off the hard drive to never, and check to see if other programs are running and shutting down in the system background. If the LAN is connected, it is best to pull it down.
Before finishing, it is best to scan the disk first, delete the files no longer needed to ensure that the process of finishing quickly and correctly.
Workaround Two:
First, the disk defragmentation tool for error-checking repair, the mouse right click the disk you want to clean up the letter, select "Properties-Tools" on the pop-up dialog, then click the "Start Check" button in the "Check Out" box, pop-up window, check "Automatic repair System file Error", click "Start", pop-up window, click "Yes" (Y) , and then reboot the computer, then reboot into the desktop, and then automatically detect the disk repair, after the repair is complete and then you can try to use the Disk Defragmenter tool.
If the fragmented file is corrupted, try repairing it with the repair tool. You can click "Start-run" to type "Chkdsk C" on the Run input box:/F command, and then when you are prompted to "check this volume on the next system reboot", now type "Y" with the keyboard to schedule the computer to reboot, check the volume, and then reboot the computer so that the computer can be repaired in the background. The repair completes to see if the fragments can be sorted.
Of course, it is possible that the above methods are used and can not solve the problem at this time if convenient to the hard drive can be formatted once, such words may be repaired oh.
