An SD card is a cross-compatible storage unit.
Look for a lock switch.
Many SD cards include a side switch that serves as a lock protection.
Inspect the card for signs of damage.
A cracked housing suggests that the chips inside are damaged.
Clean the contacts with compressed air then reinsert the card, provided it shows no other signs of damage.
Check the card for errors.
The chkdsk command on Windows reviews a disk’s filesystem and, as necessary, corrects errors.
A card inserted into a camera or other equipment supports on-equipment formatting.
A card intended for use on Windows-based computers supports formatting using a Windows-capable filesystem.
Reformatting an SD card removes its existing data.
Causes of SD Cards Not Working
