Hello everyone, Lin Fei to answer the above questions, hard disk bad road detection, hard disk bad road detection many people do not know, now let's take a look!

Hard disk is the main storage medium of computer, and many users will store some important documents and data in it. But the use of computer hard drives for a long time, it is easy to appear bad, and so on. At this time, we will face the result of data loss. My heart is really cold. Is it cold even if the hard drive is broken? Actually, you can save it! Today, Bian Xiao will take you to understand the relevant knowledge points of the bad track of the hard disk and the methods of detection and repair.

First, the reason why the computer has a bad hard disk

(1) symptoms

1. An automatic disk scan is performed every time the computer is powered on, indicating that there is an error on the hard drive that needs to be fixed. If the program does not pass smoothly, the hard drive has a bad path, or it is marked with a red "B" in some places, although the scan can pass.

two。 The speed of opening and running files becomes extremely slow, or you can obviously hear the hard disk click, and sometimes Win will prompt that you cannot read or write files.

3. The hard drive does not boot when the computer starts, and so on. You can check the hard drive letter, but you cannot operate this partition. Or the drive letter just disappears.

4. After the virus infection is eliminated, the system can not start normally, and there are prompts such as "sector not found" or "general error reading disk c".

(2) the bad track of hard disk can be divided into logical bad channel and physical bad track.

1. Bad logic: it is usually caused by improper use and operation of the software, which is called soft fault and is easy to repair by itself.

two。 Physical bad track: physical damage on the hard disk is a really bad track. Self-maintenance is difficult, and the more serious ones need to return to the factory for overhaul.

Second, how to "detect" a bad hard drive?

If your computer system starts normally, repair your hard drive directly with the disk tool that comes with Win:

1. Open the drive letter selected by my computer, right-click, and select "tool Startup check" in the pop-up drive properties window.

two。 Select "automatically fix file system errors" and "scan to recover bad sectors", and then click start to repair.

If your computer system does not boot properly, you can use the DISKGENIUS partitioning tool built into the Quick start pe system to detect bad tracks:

1. Download a u-disk boot disk production tool from Kuaishou's official website, and then make a u-disk PE boot disk.

two。 Plug the prepared USB disk into the usb port of the computer and turn it on. When you see the logo icon, press the shortcut key of U disk to enter the main menu page for getting started. Then use the up and down keys on the keyboard to move the cursor to "[02] run Quick start Win10PE" and press enter to confirm, as shown in the figure:

3. After entering the win10pe desktop, double-click the "more tools" folder on the desktop, locate and double-click the "Partition tools DiskGenius" icon in the folder, and open the tools, as shown in the figure:

4. After opening the partition tool DiskGenius, right-select the entire hard disk, and an options dialog box will pop up to select "Bad Rail Detection and repair", as shown in the figure:

5. Click the "Select hard disk" button in the upper left corner, select the drive letter you want to detect (the entire hard disk), set the detection range (default is cylindrical range), and click the "start Detection" button, as shown in the figure:

6. The software starts to detect bad tracks, and when bad tracks are found, the dialog box displays bad tracks, as shown in the figure:

7. When a bad track is encountered during the inspection, the inspection speed will be slowed down. After detection, the software reports the number of bad tracks detected, as shown in the figure:

8. When the test is complete, you can click the Save report button to save the test results to a text file for future reference. You can also click the "Save Test Information" button to display the test results

9. If you want to immediately try to repair the bad road that has just been detected, click the "try to fix" button. The software displays the following prompt, as shown in the figure:

Important reminder: bad road repair will destroy the data near the bad road! Where possible, be sure to back up the disk data first. If there is important data in the bad road area, please do not use this function to repair the bad road, but should send the hard disk to a professional data recovery center to recover the data. Bad track repair destroys data, not recovers it! In addition, it should be noted that not all bad roads can be repaired, and the types of bad roads that can be repaired by this function are limited.

For the sake of data security, it is recommended that you no longer use disks that have bad tracks. Even if the bad road has been repaired. In particular, do not store important data on it. If there is no bad track detection, or if you run the fast start software partition tool or use other software to detect bad tracks, in order to save time, you can also directly use fast start software to repair bad tracks without detection.

9. If the repair is successful, hover the mouse over the cylindrical box and prompt to display "repaired", as shown in the figure:

10. The repair is completed, and the software reports the number of bad roads repaired. Please actually test the repair result, as shown in the figure:

So far, this is the end of the tutorial on repairing bad tracks on hard drives. Finally, I would like to remind you again: bad ways may still appear and spread, it is recommended not to use it, even if you continue to use it, do not store important data!

At the end of this article, I hope it will be helpful to you.
