Precautions for daily use of SD cards

In order to avoid the SD card from being damaged again, the following points should be paid attention to in daily use:

1. Do not suddenly unplug the SD card in use

Whether it is a mobile phone, camera or card reader, if the SD card is reading data, it must not be taken out directly! Because such an operation will destroy the unique document format and structure established by different devices, it will be prone to storage errors.

2. Beware of high temperature, wet water and oil

SD card is an electronic product based on semiconductor flash memory, so it should be kept away from high temperature, oil stain, water immersion, etc. If you stay in this environment for a long time, the SD card will be easily damaged and files will be lost. When not in daily use, the SD card can be placed in the purchased card box.

3. Use card reader

Compared with directly connecting the mobile phone or camera to the computer to transmit the SD card data in the device, using the card reader to connect the SD card to the computer can not only improve the reading efficiency, but also avoid the risk of SD card damage or data loss caused by sudden power failure of the device.

4. Avoid editing files directly in the SD card

If you want to view / edit the files stored in the SD card on the computer, it is best to copy the files to the computer before operation. Especially when editing a large number of photos or video files, operating directly on the SD card will easily lead to the "paralysis" of the SD card.
