Part 4. Precautions for daily use of SD card

In order to prevent the SD card from being damaged again, the following points should be noted in daily use:

1. Do not pull out the SD card you are using suddenly

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 operation will destroy the unique document format and structure established by different devices, storage errors will easily occur.

2. Be careful 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 and water immersion. 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 matching card box.

3. Multi 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 improve the reading efficiency and 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 operating. Especially when a large number of photos or video files are edited, direct operation on the SD card will easily lead to "paralysis" of the SD card.
