If your SD card is in a write-protection situation, the SD card can’t be showing up neither. To remove the write-protect state, you need to format the USB drive and also remove the write-protection in registry editor. You can use diskpart.exe to format the removable device. Go to Run by pressing Windows key and R key, and input diskpart, click OK to enter the diskpart command prompt. Type the following command to finish the format process with enter after each:

Then you can remove the write protection state from the USB drive successfully.

However, command prompt line is not so easy as some third party software due to its complex. Here I recommend the free partition software AOMEI Partition Assistant Standard, which is much easier and simpler comparing with using CMD. You can remove the write protection state with it safely and easily.
