Disk crash recovery.

Welcome to my “Disk crash recovery.”
This morning to play the computer and found that the hard disk partition less 3, and then follow the method on the network under the DICKMAN recovery, but do not know is not restored correctly, the system appears a lot of errors, C drive cannot read. The system can not enter the WINDOW, and then intend to reinstall the system, but do not know the district lost the case of reloading the system for the original partition of the file information is a problem. I...
Unfolded
I would like to save the system inside the C drive in addition to all the data if there is no way is not only to do hardware-level data repair?

First to find Zhang start CD-ROM, the general system can be sold outside the disk can be found with a PE with the system disk, with PE into the system, if the data is not a lot of words, it is recommended to find a U disk you need to backup data, if The amount of data, it is recommended to find a mobile hard disk. Data copy out, you can rest assured that the overall format, and then do a system, backup, OK.

Into the PE out of the C drive other than the data on the OK, it is best to be a hard disk test, with the installation of the basic discs has a deep set of tools, there is the detection of hard disk software.

Hard disk and people, with the "age" of the growth, it is easy to produce a variety of problems, and hard disk "bad sectors" (or disk "bad sectors") is one of the more common problems. Hard disk bad sectors of the reasons, in addition to the quality of the hard disk itself and the reasons for aging, the main is usually not used in the hard disk, such as memory is too small so that the application software on the hard disk frequent access and read and write, the hard disk too often defragmented, Improper overclocking, power quality is not good, the temperature is too high, poor dust, vibration and so on.
1. hard disk has bad track symptoms
a. When reading a file or running a program, the hard disk repeatedly read the disk and error, prompt file damage and other information, or to go through a long time to succeed; sometimes even a blue screen.
b. Each time the system starts, Scandisk will scan the disk error automatically 
. In the steward when the garbage scan, you will find the size of a class of garbage shows abnormal (such as significantly beyond the hard disk size)

 But to add that, as colds are also common cold and avian flu, although the initial symptoms may be similar, but if suffering from H7N9, it can cure the fact ... ... is also a qualitative distinction. Hard disk bad sectors is the case, we usually bad sectors are divided into "logical bad sectors" and "physical bad sectors", the former is soft bad sectors, usually the use of the software or improper operation caused by the hard disk has little effect Through some tools and software or formatted that can be self-repair. The latter is a real physical bad sectors, it shows that your hard disk tracks have physical damage, can not be used to repair the software, and physical bad sectors with "infectious" to the surrounding diffusion, resulting in the data stored in the vicinity of bad sectors are also in Dangerous situation ("bad sectors in the H7N9" there are wood ah). In this case, we should as soon as possible bad sectors "isolated" open, that is, change the hard disk partition, hidden bad sectors, and quickly do a good job backup work, to avoid the loss of valuable information. If you are uncertain, it is recommended to find a professional to solve.
2. If you have these "symptoms", how do we diagnose whether the hard disk bad sectors
We can use the most simple way, that is, windows comes with chkdsk tools to diagnose whether the hard disk bad sectors, then the chkdsk tool where?
Open the run (shortcut key file: /// C: /Users/ashhuang/AppData/Local/Temp/msohtmlclip1/01/clip_image004.gif+R), enter cmd.exe open the command prompt, enter CHKDSK C: / F this Class parameters.
