Hard drive C5 and C7 warnings may be a sign of hard drive failure and require attention. PHP editor Strawberry will introduce to you the meaning of C5 and C7 warnings, as well as possible measures to be taken when these warnings appear. The following content will elaborate on the relevant knowledge of hard drive failure to help everyone understand the symptoms, causes and solutions of hard drive failure so that timely action can be taken to protect data security.
C5 is the number of sectors waiting to be mapped, and C7 is the CRC error. C7 is generally fine, but C5 means the hard drive is about to fail or has already failed. Let’s talk about it in detail below:
1. Remapping sectors Remapping sectors (05 and C5) is like this. In fact, the real capacity and nominal capacity of the current hard disk are different. For example, you bought 1T, but the actual capacity is 1T. It may be 1.2T. Once there is a problem with a sector, the hard disk's own firmware will add the sector to the P-list or G-list, and then find a sector from the extra 0.2t to replace the bad one. This is remapping. sectors. To some extent, this is the difference between server hard drives and ordinary hard drives. Servers have more spare space and this mechanism is more complete. This is equivalent to being a substitute player on the court. When a player on the field is injured, he or she can be replaced, so although a player is injured, it does not affect the game. Remapping sectors is a backup mechanism adopted to avoid data loss. When there are enough spare mapped sectors, data security is not affected. However, if players on the field continue to be injured, the reserve players will always be used up; similarly, the spare mapping sectors will also be used up. Once it is used up, your hard drive will have physical bad sectors. Moreover, usually the area of bad sectors will continue to expand. Therefore, it is normal to have a small number of remapped sectors and does not affect data security. You can use Hdtune to test and see the health. If the data in the remapped sectors is increasing rapidly, it means that bad sectors are spreading. The spare sectors will one day be used up, and bad sectors will appear. Your data is at risk. If your hard disk has been used for two or three years and has a small number of remapped sectors, that is normal. But be careful that the number is not too large and does not grow rapidly. If so, and you feel a little laggy, it means the hard drive is dying. Back up your important data and continue using it until you feel the lag is unbearable. Then get rid of it and buy another hard drive.
2. UltraDMACRC Error Count "UltraDMACRC Error Count" (C7) does not have a very specific explanation. Generally speaking, it means that the hard disk interface is damaged. Generally, the hard disk will be plugged in and out many times normally, and there will be this yellow alarm, but don't worry. , please carefully check the SATA interface of the motherboard and the SATA interface of the hard disk to see if there are obvious signs of wear or burnt. If there are no such signs, the hard disk can be used safely. If you use several versions of HD-TUNE software for testing, you will find that some HD- TUNE has yellow alerts, some don't. The code is generally C7, but different manufacturers have different definitions of this code. Using general software, such as hdtune, to measure C7 errors may not necessarily be UDC errors. In addition, if this error occurs on the SSD, don’t worry. Because the smart definition of SSD is different from that of mechanical disk. This error is often detected in new disks as well. fine.
The computer’s hard drive is one of the core devices for storing data and is crucial to the normal operation of the computer. However, due to long-term use, hardware aging, improper operation, etc., hard drive failure may occur, resulting in data loss and system crash. Therefore, it is very important to detect and solve hard drive failure problems early.
Before performing hard drive failure detection, it is necessary to understand some common types of hard drive failures. Common hard drive failures include:
Physical failure: Damage to the mechanical parts of the hard drive or damaged sectors. Logical failure: Data loss due to virus infection, file system error, or unexpected shutdown. Circuit failure: Problem with the hard drive circuit board or hard drive connector. Bad Sectors: Corrupted areas on a hard drive where data cannot be read or written. Noise problem: Abnormal noise coming from the hard drive indicates that the hard drive is experiencing problems.There are many software tools that can help us detect hard drive failures. The following are some common software tools:
{Forced Allocation Disk Tool} {Disk Defragmentation Tool} {SMART Hard Drive Monitoring Tool} {Hard Drive Health Detection Tool}These tools can help users detect the health status, life prediction and data of the hard drive issues such as integrity. By using these tools, users can detect potential hard drive failure problems early and take appropriate measures.
When facing a physical failure of the hard disk, first make sure that the computer has been disconnected from the power supply. Then, you can use the following methods to detect hard drive physical failures:
Check whether the hard drive cable is loose or damaged. Try replacing the original cable with another one. Plug the hard drive into another computer and check whether it can be recognized normally. Use professional hard drive testing equipment to conduct a comprehensive test on the hard drive.For logical faults, we can try the following methods to fix them:
Use data recovery software to try to recover lost or damaged data. Check and fix file system errors. Run a virus scanner to remove any potential viruses. Make sure the computer does not shut down unexpectedly and try to avoid sudden power outages.Preventing hard drive failure is equally important. The following are some preventive measures:
Regularly clean the dust inside the computer and maintain normal ventilation and heat dissipation of the hardware. Use a reliable power supply to avoid voltage instability causing damage to the hard drive. Back up important data regularly to prevent data loss. Check and update system and hardware drivers regularly.To sum up, it is crucial to detect and solve hard drive failure problems early. By using the right tools for detection and taking appropriate measures in a timely manner, we can minimize the impact of hard drive failure on your computer and data.

Your laptop disk is in the warning period.
It is recommended to back up important data. It should be fine for now. But I can't hold on for long. Can only be replaced with new ones. Hard drives are valuable and data is priceless. Act early.Cannot be repaired. Because they are restorations themselves.
1, 05, C4, C5 are all aspects of the same thing. They are different counters for the hard drive's self-healing mechanism.
2. 05 is the number of bad sectors found that need to be mapped and repaired. C4 is the number of repairs. The number increases regardless of whether the repair is completed. C5 is the number waiting for repair.
3. Generally, a small number of numbers is normal, indicating that the hard drive’s self-healing function is sound. But if it is yellow, it usually means that there are too many bad sectors that cannot be repaired. You can check the bad sectors, which usually means there are bad sectors. If there are not many bad sectors, you can use relevant software to repair them. If there are many, just replace the disk. For example, diskgenius can repair a small number of bad sectors.
Thanks for the invitation, the mechanical hard drive is quite heavy. . . Knocked. . If C4C5 is yellow, it means there are bad sectors. Usually the disk surface is scratched by the magnetic head. The life of your disk may not be long. In this case, the more you use it, the more bad sectors you will get. It is recommended to low-level format the backup data. It is estimated that it can still be used for a while. To be on the safe side, replace it. After all, data is priceless
The hard drive is an important part of the computer. It Stores important computer data and programs. However, hard drive failures occur from time to time and may cause the computer to not function properly. This article will introduce some common hard drive failures and their analysis methods.
Hard drive failures mainly include physical failures and logical failures. Physical failure refers to damage to the physical components of the hard drive, such as heads, disks, motors, etc. Logical failures are caused by file system errors, virus attacks, etc.
For physical faults, professional hard disk tools need to be used for detection and repair. If the hard drive cannot be repaired, it will need to be replaced with a new one. For logical failures, you can analyze and solve them through the following methods:
Check the file system: Use a disk management tool or a specialized file system check tool to check the file system for errors and repair them. Use anti-virus software: Check your hard drive for viruses or malware and remove them promptly. Back up data: Back up important data regularly to prevent data loss or damage.In addition to the above methods, you can also refer to the experience sharing on some professional forums or websites to learn more about the analysis and processing methods of hard drive failure.
When analyzing hard drive failure, you need to pay attention to the following points:
