Fix a Card by Trying CHKDSK Command to Check for Memory Card Errors
Included in all versions of Windows is a command-line utility for checking the file system and file system metadata of a volume for logical and physical errors. This utility is called CHKDSK , and it’s actually much easier to use than most people think. To fix a corrupted SD card using the CHKDSK command : Type “cmd” in the search box on the taskbar and select Run as administrator . Enter the following command (make sure to replace X with the letter assigned to the SD card you want to fix) and press Enter: chkdsk X: /f (The /f parameter tells CHKDSK to fix all memory card errors.)
