SD card prompts an error and cannot be formatted. What should I do? I believe many friends encounter such problems, but don't know how to solve them. Let me introduce them in detail. Let's have a look with those who won't!
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!
