Win7 detects a hard disk error after booting. Please backup the file immediately.

A friend who encounters this situation needs to pay attention. Although I don't know what the current hard disk is, I can still use it in the computer. Next, the first thing we need to do is to back up the data on the hard disk to prevent data loss. Then enable the system check to find the reason.

After the data backup is completed, we can handle it in two ways:

1. System problem: turn on the computer - drive letter right - attribute - tool - check error --- Start checking. If the computer finds a hard disk problem, it will enable automatic system repair. If you can't fix it, you can try the following method.

2, hard disk problem: format the whole disk, and find a professional to detect whether the hard disk has bad sectors, if there are bad sectors, you need to change a hard disk.

No matter what method is used, the first operation is to back up the data. After all, the data is priceless. The price of the hard disk is now cheaper. You can buy a 1TB hard disk for three or four hundred. Small lost. I hope that the above methods and suggestions can be helpful to everyone.
