Checkbox is a testing framework used to validate device compatibility with Ubuntu Linux. It’s the testing tool developed for the purposes of the Ubuntu Certification program.
To prevent the inserted storage from failing to mount twice, first ensure it is unmounted.
Because the OS will auto-mount the inserted storage, the existing subprocess.call(["mount", device_to_mount, FOLDER_TO_MOUNT]) command will cause an error if the format of inserted storage is NTFS.
Perform an umount on device_to_mount (e.g., for the media card in #1587, it would be umount /dev/mmcblk0p1) before attempting to mount it again to avoid this issue.

Run checkbox-cli run com.canonical.certification::mediacard/sdhc-storage-manual
Insert mediacard as prompt:
--------- Testing insertion ---------
INSERT NOW
Timeout: 30 seconds
3. After detectd the card, checkbox will do the read/write test.
### With the above change, it shows:

Mount is denied because the NTFS volume is already exclusively opened.
