When the SD card is not properly ejected when it is used improperly or pulled out, the SD card will be damaged, and the above problems may also occur in this case.

2. Remove the SD card and reinsert it into the device

If your SD card unexpectedly disconnects or vanishes while in use, remove it to inspect for dirt or an oxide layer on the metal contacts. Clean any debris with an eraser, gently wipe with a soft cloth, reinsert the card, and check if the issue is resolved.

3. Update SD card driver

If your SD card is disconnecting or disappearing, it could be due to an outdated driver. To resolve this, update your SD card driver to the latest version by following these steps on Windows.

Step 1: Boot up your Windows computer and insert the SD card through a card reader. Press Windows icon + R to launch the Run dialog. Type devmgmt.msc into the field and select OK to open the Device Manager.
run the command devmgmt
Step 2: Next, expand the “Disk Drive” list, right-click the SD card that you want to update the drive, and select the (Update Driver) option.

4. Format the SD card

If the SD card frequently disconnects or vanishes and other troubleshooting methods fail, consider formatting it. This may resolve issues caused by the card reaching the end of its write cycle or severe damage. Remember, all storage devices, such as SD cards, have a limited lifespan. Once this lifespan is exceeded, normal use is impacted. To prevent data loss, avoid storing critical files on an SD card close to its lifespan’s end.
The specific operation steps are as follows:
Step 1: Connect the SD card to the computer through a card reader, and press the (Windows+X) key on the keyboard at the same time. Then in the pop-up list, select the (Disk Management) option.
