What is the reason why the SD card is damaged for a while, sometimes it s okay, sometimes it s damag

Poor contact, rub the contact point with a pencil!

The SD card is the memory card, let the phone restart once, and then restore the SD card with one click.

Causes and workarounds:

1. The SD card of the mobile phone is not in good contact with the mobile phone, the solution: reinstall the SD card.

2. The SD card of the mobile phone is corrupted, the solution: reformat the SD card.

3. The SD card of the mobile phone is damaged, the solution: replace the SD card with a new one.

4. The SD card cannot be read due to mobile phone software or reasons, solution: restore the mobile phone to factory settings or flash it.

5. Mobile phone hardware problems, such as SD card slots are broken, solution: after-sales inspection and maintenance.

Plug it back in again and take a look.

No, just try formatting.

It still doesn't work, and it's damaged.

Maybe the SD card is gray or something, take it out and wipe it and try again.

Hello 1, it may be that there is a virus in the memory card, or there is an error in the memory card.

2. You can take off the memory card and connect it to the computer with a card reader.

1.Because of the oxide layer of SD card gold finger after being damp and wet!! Damaged!!

2.Because the air is dry and comes into contact with items with static electricity, it leads to static electricity breakdown!! Wear a sweater in autumn and winter, try not to hold the SD card in your hand, and do not touch the gold finger to avoid the harm caused by static electricity!!

The chip is damaged due to prolonged high-temperature work!! When you're done with it, take it off the card reader, right? Reduced point calorific !!

Formatting, you can reformat it.

Hello! This type of problem is usually caused by memory card failure, which can be caused by the following:

a. Physical damage to the memory card.

If the memory card is determined to be physically damaged, the only way to do so is to replace it with another memory card.

If you insert the memory card into another working mobile phone or card reader, if it does not work properly, it can be judged that the memory card is physically damaged.

b. Problems with metal contacts on memory cards.

Both the metal contacts on the memory card and the contacts in the mobile phone card slot can oxidize and cause dirt. This will lead to poor contact, which of course will affect the phone's reading of the memory card.

Just like dealing with the dirt on the gold finger of the memory stick on the computer, cleaning the above parts with a leather wipe and then using a white paper will solve the problem caused by this problem.

If the above measures are ineffective, only card replacement (or repair of the mobile phone card reading slot) can be considered.

Because the number of reads and writes of the SD card is limited.

It's usually a matter of current. Because the data voltage of the SD card is only 5V, it can be damaged if you are not careful. For example, static electricity, or the card reader is not good.

If what's in your card doesn't matter right now, just format it, that's what I used to do....But if it's not used after formatting, it's a broken card.

If the SD card is damaged, it can't be used anymore, it can't be put in, and it can't be read.

It is estimated that the SD card is broken and the card is going to be replaced

Abnormal power on/off, caused by an instantaneous short circuit when the card is inserted and unplugged without shutting down.
