Solution: Your SD card might contain files which is not supported by your device. Example: copy the bootable Windows OS installation files to your SD card, then when you insert the card, you will get this error 'SD Card Blank'. This is because sd card contain files which are not recognized by Android OS. So, manually delete these files to avoid the error.
