Not only the mobile phone, but also the computer sometimes prompts the SD card incorrectly and cannot be formatted. What should I do? In fact, it's not difficult to solve. Let me give you a detailed introduction. Let's have a look with friends who won't!
Solution to the problem that the computer SD card cannot be formatted
Tools / raw materials
Computer, Windows XP operating system, network, SD card, system patch and other tools.
Protection switch:
Because some SD cards have write protection switches, if they are accidentally turned off, they can only read data, not write data to this card at will.
At this time, just toggle the protection switch on the side of the SD card to turn off the write protection and read and write data at will.
Format:
Insert the SD card to pop up the prompt that it has not been formatted. If it is a new card, it may indeed need to be formatted.
Right click the drive letter in the operating system of the computer → format.
If the SD card works well in the mobile phone (can see the data), but it prompts to format in the computer, and there are important data. If you don't want to format, you need to pay attention.
If the SD card uses exFAT format, if it is inserted into the Windows XP operating system, there may be a prompt that there is no format. That is because there is no format mode in the format mode, so there will be an error prompt.
At this point, you can update the Windows XP system patch (kb955704).
Or check in the control panel (check show update). If there is already this patch, there is no need to update it.
If you are in the windows7 operating system, you do not need to update the patch. This function comes with it. If there is still an exception prompt, you should find the reason from other aspects.
The above is the solution of SD card prompt error and unable to format. Do you understand? I hope it can help you!

1. Generally, more than 80% of computer system faults are software faults. At the same time, most software faults are relatively easy to deal with, while most hardware faults are caused by peripherals. Therefore, the analysis and fault finding should be carried out in the order of "software before hardware, external before internal".
2. Common software faults.
A. error prompt: in case of software failure, many errors can be captured by the application software or operating system and give corresponding prompts. Such failures are generally caused by software defects, software conflicts, improper configuration or wrong operation.
B. application software fails to start normally: such failures are generally caused by software conflict, wrong operation, improper configuration or virus.
3. Handling methods of common software faults.
A. use anti-virus software: in case of inexplicable slow down or error of the system or application, scan the whole system with anti-virus software to determine whether the system is poisoned.
B. single application system failure: for single application system failure, the application is generally reinstalled. If you are familiar with the system, you can check the system configuration first and then decide whether to reinstall the system
4. Causes and treatment methods of common hardware faults.
The causes of computer hardware failure are mainly related to the use environment, users' operation habits, natural aging of hardware and poor quality of hardware products. Under normal circumstances, the hardware failure of the system can be eliminated as long as the faulty hardware equipment is found and replaced.
5. When the computer system has a fault, first confirm the fault phenomenon through observation and inspection, then analyze the fault phenomenon, judge the possible cause of the fault of the computer system according to the corresponding relationship between these fault phenomena and possible causes, and then use the troubleshooting method to eliminate the impossible fault causes, so as to gradually determine the fault causes. When the fault causes are determined, Then start the maintenance.
6. The above contents involve relevant computer knowledge. If non professionals suggest to find enough experience before actual operation, some complex computer faults need to be repaired by professional maintenance points and professional maintenance personnel.
