To recover data from a formatted SD card manually, you can try using built-in operating system utilities like Windows' "File History" or macOS' "Time Machine" if you had these features enabled before formatting. However, if these options are not available or unsuccessful, a more reliable approach is to use a dedicated data recovery software like the BLR Data Recovery Tool. This tool scans your formatted SD card for any recoverable files and can restore them even if the file system has been altered or erased. The BLR Data Recovery Tool offers a user-friendly interface and advanced algorithms to maximize the chances of recovering lost data from formatted SD cards.
