The phone memory card can t be read after changing the number

I'll take the 200 points. This problem should be solved with logical ideas, and you can also solve the problem with this method in the future.

You have now lost 2 things, the memory card and the data on the memory card.

Data: Use a card reader to quickly pour it to the computer, and the memory card generally does not put important information, which is easy to lose.

Memory card: There are several factors that can cause a card to be unreadable

1. Prepaid card (dynamic and Shenzhouxing).

2. Memory card.

3. Mobile phone. Solution: 3 factors, shield 2 of them, and confirm by substitution method.

1. Prepaid card (dynamic and Shenzhouxing): The mobile phone and memory card remain unchanged, replace the dynamic and Shenzhouxing, and finally find someone else's prepaid card to try it, you can confirm whether the prepaid card is the real reason.

2. Memory card: The mobile phone and the stored value card remain unchanged, find someone else's memory card (the same type and capacity, and it is the card recognized by your mobile phone), you can confirm whether the memory card is the real reason.

3. Mobile phone: the memory card and the stored value card remain unchanged, find the same mobile phone or recognize the mobile phone that can be used as a memory card to try it, you can confirm whether the mobile phone is the real reason.

If the above steps still do not solve the problem, you need to block one factor at a time and try 3 more times. If there are 3 factors at the same time, then you can buy another set as garbage, so there is no need to do the 3-factor experiment.

As long as you determine which factor causes it, it is easy to do, for example, if the memory card is broken, check the settings and appearance of the memory card, and generally it cannot be repaired. If the phone is broken, check the setting parameters, appearance, etc., and it can generally be repaired. If the stored value card is broken, you can only change it or buy it again, and it is difficult to repair it (if you have a lot of money in it, go to the business hall to change it).

I am a quality worker, and I am good at analyzing the causes of quality accidents, which is a common idea, which may be helpful for you to solve similar problems in the future.

You change back to the card of Shenzhou Xing and see if the screen is still white. If not.

You're going back to the Dynamic Zone. Then plug in the memory card, and connect the phone data cable to the computer.

See if you can detect the memory card, and if you can, format the memory card.

Then disconnect. Restart your phone and you're done. Hehe, I've encountered it too

How did you choose the formatting?

The computer uses FAT32, and the mobile phone recognizes FAT16. Connect your phone to your computer, then click on "Start" - "Run" and type "cmd" and then type in format x, x is the symbol for your phone card. For example, if you have a C or D disk in your computer, an E disk will come out after plugging in a USB flash drive.

That's x is e:.

If the card is broken, you can try to fix it with the hard drive tool.

This is also the case with my previous Nokia, and the format must be correct!

Listen to me, you borrow a phone and plug the card into someone else's phone.

1. If you can read it, you have a problem with the slot, and the phone is repaired.

2. If you can't read it and the memory card is broken, buy a new one.

There are two outcomes.

Speed replied to me.

Did you turn on the write protection of the memory card? (if any).

The memory card is formatted with the computer and then put it in the mobile phone to turn it on.

1. The mobile phone card is broken or the contact is poor, resulting in the mobile phone memory card cannot be read.

Solution: If it is a poor contact, this is a good problem to solve, take out the card, use the eraser to erase the gold finger of the memory card, remove the oxide layer on it, and then put it in the mobile phone to try. If that doesn't work, pry the tentacles inside the memory card holder higher, or apply a layer of glue on the back of the memory card to increase its thickness.

2. The mobile phone memory card can not be read due to poisoning, and the solution: There are many cases in this case, and the poisoning will also lead to the problem that the memory card cannot be formatted, which is generally not easy to repair. If it is a virus that causes the mobile phone memory card to not be read, it is necessary to format the memory card, and the memory card that can be formatted can generally fix the problem.

A memory card that cannot be formatted is not easy to repair, and of course it can also be repaired with the help of memory card repair software. If there is important data in it, then you have to use a data recovery tool to recover the data inside, pay attention to do not write data to the memory card after formatting, which will cause the recovery file to be incomplete.

The file you want to delete is running, so it can't be deleted.

You click on the properties of your memory card on your computer to see if it is set to read-only, and antivirus is recommended.

The memory card is not broken, but the phone is associated with the files in the memory card, so it can't be read, so you have to delete some

If the memory card is corrupted, just format it with a computer.
