Save lost hard drive data

During the use of the computer, there are often some unexpected things, such as software settings, system infections, accidental deletion of files, etc., which will cause data corruption or loss in our computer. If God gives you a chance, how do you know how to save these important data? Come here, see below.

How is the data lost?

One of the unfortunate: data loss caused by misformatting or accidental deletion.

In this case, as long as you do not write new data to the partition where the data is lost, the data recovery software has a high success rate for data recovery, and the recovery rate is close to 100%. But if you start with professional data-removal software to delete data and repeatedly delete the data, then the data is basically hopelessly restored.

Unfortunate 2: Loss of data caused by viruses.

Because the virus destroys the hard disk too much, and most of the damage can not be easily restored with the general software, so ... when you encounter the virus destroying the hard disk, you pray, the success rate of data recovery is only about 30%.

Unfortunate 3: Partition table missing /error.

The infected disk drive letter suddenly disappears, the drive letter cannot be opened, or the partition table is lost by human operation, such as the new partition, merge, conversion, expansion, and sudden power failure during the work process, resulting in loss of the partition table. Wait. 100% of data loss caused by normal human operations can be recovered. If you back up the partition table, the success rate of restoring data will be greatly improved (see "What should I do if the hard disk partition is broken?").

Unfortunate 4: Data is lost after the system is reinstalled or incorrectly "Ghost".

This type of problem is generally due to the fact that the data has been written to overwrite the source file, the recovery rate is not satisfactory, about 30%.

Unfortunate 5: Loss of data caused by power failure during operation.

This type of data recovery depends on the situation. If the data is not saved and the program used does not have the auto-save function, it is generally difficult to recover. Programs like Office XP and above generally automatically back up and automatically recover.
What should I do if the data is lost?

One of the conditioning: If you do not have data recovery software installed, do not perform other reading and writing operations on the hard disk after data loss. Do not install or store any files and programs on the hard disk, otherwise they will overwrite the files to be restored, which will bring great difficulty to the recovery of data and affect the success rate of the repair.

Special reminder: When installing Windows system, you should install the data recovery software, and perform the recovery operation immediately after the file is deleted accidentally, so you can restore the deleted files.

Conditional Reflex 2: If the lost data is in the system partition, please shut down immediately, take the hard drive down, hang it on another computer as the second hard disk, and resume the operation on it. If your data is very important, especially after formatting and writing data, it is best not to risk repairing yourself, or to ask a professional data recovery company to recover.

Conditional Reflex 3: When repairing corrupted data, be sure to back up the source file before repairing it. If it is a mistakenly formatted disk partition and a file that is deleted by mistake, it is recommended to use Ghost to clone the misformatted partition and the partition where the file is deleted by mistake, and back up the original disk partition status so that data recovery can be performed again in the future.
