System read-write efficiency and defragment disk

Failure phenomenon: The machine shut down normally, every reboot system will appear long disk scan, scanning process system prompts to find a hidden directory error, automatic repair can enter the system normal operation.

Troubleshooting: The author in the absence of any restore card or restore software, the system files will be repeatedly damaged, let people first suspect that the virus destroyed some files. Immediately with the latest version of the anti-virus software comprehensive killing, no traces of any virus found. It appears that the cause of file errors is still more difficult to analyze.

The stupidest way to solve the problem is to format the system disk and reinstall the system. But this is too much trouble, and it is not conducive to the accumulation of fault handling experience, so still decided to first try there are no other simple method feasible.

Then open the attachment/System tools in the System Restore program, select an earlier time to restore, the problem remains after restore. Also try to run the Disk Defragmenter in the attachment, select C disk to defragment. After more than 10 minutes to wait, defragmentation end, and then restart the computer, this is no longer a disk scan phenomenon, the failure to completely eliminate.

Experience Summary: Hard disk used for a long time, the location of the file will become fragmented. Disk fragmentation generally does not cause system problems, but in the case of too much fragmentation, it can cause the system to look back and forth while reading files, not only reducing the working efficiency of the hard disk, but also increasing the likelihood of data loss and data corruption. In the long run, hard drive life will be shortened. Therefore, we should usually develop regular disk debris habits.
