What To Know
- Check if the SD card has a write-protection switch and ensure it is set to the “unlocked” position.
- If the switch is not present, try using a different SD card reader or connecting it to a different computer.
- Try formatting the SD card using a standard file system such as FAT32 or exFAT.
SD cards, the ubiquitous storage devices used in various electronic gadgets, are prone to corruption due to several factors such as improper handling, electrical surges, virus attacks, or simply aging. A corrupted SD card can manifest in various ways, including inaccessible files, read/write errors, or even complete failure. If you find yourself with a corrupted SD card, do not despair; formatting can restore its functionality and salvage your valuable data.
