How to know the extent of damage to the C drive and what to do if the C drive is damaged

The situation you are talking about is prone to physical bad sectors. However, the protection ability of the current hard disk is relatively strong, and the setting of the microcomputer power supply is also different from the ordinary power supply, which has a certain protective effect, so it may not be that your hard disk will be damaged.

After the C drive is damaged, the system usually fails to boot or the program often crashes.

You can run the chkdsk c: command or use a hard disk tool such as hd tune or crystaldiskinfo for more detailed detection.

It is useless to reinstall the system until the bad sectors are repaired.

If the hard disk is still relatively new, but the C area is damaged, you can use PQ and other software to shield the previous part of the damaged place and use the later part. For more information, please refer to the relevant articles, which are many on the Internet. However, before processing, if possible, back up useful content and data.

As long as you're not running the hard drive at high speed at the time, you won't have a problem.

But the power is cut off at high speeds.

There may be physical bad sectors! ~

The so-called physical bad sector means that the channel of your hard disk cannot be used.

It's useless to reinstall the system! ~

But you can separate it into a separate section, and you don't need it! Got it?

It doesn't seem to cause bad sectors if the power is cut off during finishing. You right-click on the C drive, tools, disk check to see, if the repair is not good, it doesn't matter, just format it. Power outages generally do not cause physical bad sectors.

This is a problem with the disks, please fix it (fix it for each disk or just fix c).

Built-in disk repair method:

The specific steps are as follows: select the drive letter c in my computer, right-click the right mouse to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair it at boot after automatic shutdown, win7 select the disk check button according to the plan).

Bad sectors on the hard drive will lead to corruption or loss of computer system files, computer failure to boot or freeze. Hard disk bad sectors can be repaired using NDD Disk Utility or Scandisk.

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it, if it doesn't work, you will have to replace the hard disk, or overhaul it).

Please run the hard disk detection tool chkdsk to detect the hard disk, it is possible that the hard disk has bad sectors.

2. Use CHKDSK Disk Repair Tool to repair the disk.

On the desktop, press win+r, enter cmd and press enter to open the command prompt window;

Enter the following command in this window: chkdsk c: f r Enter will start the chkdsk disk check tool to scan the C partition and check other partitions similarly.

There are different definitions of hard disk damage, the most serious is that the hard disk cannot be recognized and cannot be read and written, and the second most serious is that the hard disk has physical bad sectors.

For the former, the judgment method is relatively simple, which can be judged by the following methods:

1) After booting up, enter the BIOS and confirm whether the BIOS recognizes the hard disk, 2) Mount it to other normal systems, open the disk manager, and confirm whether there is a mounted hard disk listed in it For the latter, you need to perform a hard disk scan to confirm, you can use DiskGenius or HDD Tune Pro software to scan.

Start-run-chkdsk c:f OK, in the interface that opens, press the prompts, type yRestart your computer and let it run automatically. ok
