However, it’s important to note that this process modifies the file system, and in some cases, may cause further data loss if used incorrectly. For detailed guidance, you can also check the official Microsoft documentation on CHKDSK.If you are not confident using CMD, consider starting with professional corrupted SD card recovery software for a safer approach.
