Mobile phone memory card read and write problem 20

If you have a problem with storage, find a data recovery one.

There are generally three ways to recover an unusable phone memory card:

1. Formatting.

There are many netizens who will say that "newly bought cards must be formatted", but in fact, this statement is not correct, and some cards can be used without formatting. But if you still want to format the memory card, then Dr. wants to tell you that it is best to use a mobile phone for formatting, but there is one thing to note: due to the CPU speed and interface limitations of the mobile phone itself, the speed of formatting the card is slow, so be sure to keep the phone fully charged.

According to the doctor's experience, it takes about 6 minutes to format a 256M card at a time, so the battery of the phone should be kept at least 3 bars as much as possible!

Sometimes the format of the mobile phone will fail, at this time, don't conclude that the card is broken, you can use the computer to format it again, but the formatted "format" must be selected "fat", otherwise the formatted card will not be recognized by the phone. If the computer can't be formatted either, you can use the "mmcmedic" software to repair it again. This software works with MMC and RS-MMC cards, not with SD cards.

However, the repair of the SD card is relatively simple, and you can use a PDA or digital camera to format it.

2. Memory card repair.

After formatting, some cards will be unusable or there will be various errors in the process of use, then you can use the "Disk Utility" in the computer system to repair. Connect the card reader, then right-click on the drive letter where the memory card is located, select "Properties Troubleshooting", then select "Automatically fix file errors" and "Scan and try to recover bad sectors", but it may take a long time, so be patient.

3. Data recovery in the card.

When the memory card is deleted or formatted by mistake, the data in the card can be recovered as long as the data is not re-entered. If you have already lost a new file, you can sometimes recover part of the original data in the card, depending on the size of the new file. Here's how:

The tools we need are a computer, a card reader, and EasyRecovery software.

Please select the SD card on your phone, format it, and then take it to your computer to copy the movie.

The format of the mobile phone card should be EXFAT, and the general computer format is FAT or FAT32 format, which cannot be recognized by the mobile phone.

It may be that there is a problem with the formatting format, the formatting format is divided into fat32 and fat16 (fat) for mobile phone memory cards, it stands to reason that it should be the kind of 16, you try both to see!

The quality of the card.

Estimated virus pouring.

1. It is recommended to back up the memory card first, and then format the memory card.

2. If the memory of the mobile phone is insufficient, it is recommended to restore the factory settings, and you need to back up important data in advance.

3. You can also flash the machine, be careful not to flash the machine casually, which will lead to the instability of the system.

4. In a broad sense, mobile phone system memory is divided into "mobile phone running memory" and "mobile phone non-operating memory". The "running memory" of a mobile phone is equivalent to the memory (or memory module) of a computer; The "non-running memory" of the mobile phone, that is, the ROM and hard disk of the mobile phone, is the internal memory of the fuselage (referred to as the fuselage memory), which is equivalent to the hard disk of the computer.

There's a little switch on the memory card that you turn off, you turn it on... Close is on behalf of locking, so can read but not take... Open the representative can write, and you can change it at this time.

According to my preliminary judgment, your mobile phone card is an informal product, which is mass-produced with a small capacity and a large capacity, and the general performance is:

Small files can be used completely, but if you install large files and exceed half of the total capacity, there will be problems. Sometimes it causes data loss and display memory card corruption without formatting.

Now the number of such memory cards and USB flash drives on the market is huge, pay attention to it next time you buy it!

The specified path cannot be found, because the connection between the computer and the mobile phone memory card is disconnected, that is, the mobile phone is no longer connected to the computer, the computer does not know where to copy the file, your problem may be caused by the loose interface between the mobile phone and the computer, do not move the mobile phone and data cable when transferring movies and other things.

Upstairs is all!

He is a memory card forbidden to write!! You can't delete something! The same goes for my memory card.

It hasn't been fixed until now!

Poisoned or not plugged in well! Take out the memory card and put it on another card reader or mobile phone to try, if it doesn't work, it's poisoned, and if the file is not important, format it!
