Data security is very important, as network maintenance personnel will often encounter similar problems. I often go to my clients to help them save the lost data. Data is very important to customers, so how can we prevent data loss?

1 when we use the hard disk, especially when reading data, we must not cut off the power.

2 hard disk is most afraid of shock, such as notebook, or mobile hard disk, be sure to handle it gently.

3 to back up important data regularly, if possible, it is safest to do remote backup as banks do.

4 be careful to use some tools and software for disk operation, such as NDD,HDDREG and so on.

Try not to store important data in the mailbox.

6 do not store important data in C disk.

7 install system patches in time to prevent data theft.

Let's talk about the problems of data recovery and data repair.

Let's take a look at how to do data recovery for customers.

We have to communicate with the customer to ask the reason for the data loss, such as misoperation or hard disk failure, and after the failure, it is also very important for the user to do those actions.

Then, analyze the cause of the problem, which is mainly divided into two categories.

In one case, the system crashes, and the important data is stored on disk C or on the desktop of disk C. because the computer cannot boot properly, the data cannot be found.

There is the customer unit's computer C disk installed with important software or other important documents, at this time can not simply use the method of reinstalling the system, how to solve this problem? WINPE is recommended here. Just find out the important documents and copy them.

Another situation is the problem of the hard disk, which mainly includes that the hard computer suddenly does not recognize the hard disk, or that a partition cannot read the data, or that the file is deleted by mistake.

If the hard drive is not recognized by the computer, please check to see if the connection is normal, or check it in BIOS.

If the hard drive has sound, please find a professional hard drive to recover the data manufacturer.

If the hard disk computer can recognize or mismanipulate the file, then we can use some software to recover, such as DISKMAN,EASY RECOVERY, FINAL DATA and so on.

Let's take a look at another situation. The hard disk can be found, the partition can also be read, and the files in the partition can also be found, but the files cannot be opened, such as WORD,EXCEL. At this time, the problem is much simpler. What we need to do is data repair. The commonly used software is as follows:

OFFICE file repair software

MP3 file repair software

Audio and video repair software

PDF repair software

These software can be found on the Internet, there are many.

Let's talk about the password again.

Sometimes due to various reasons, the password is forgotten, what should I do?

You can find some password removal software or password cracking software, there are many on the Internet.

Finally, add two points.

1 if it is in NTFS format, do not rashly reinstall the system, because if some files are encrypted, even reinstalling the system cannot be read.

2 if some drive letters are lost, you can add them in disk management.
