2. Plug the external card reader and insert the formatted memory card
3. Verify if the memory card mounted and visible on File Browser
4. Remove the memory card from the card reader
5. Verify if the mounted memory card removed from the File Browser

Expected results
================

The mounted memory card identifier should be disappear after remove the
memory card

Actual results
==============

The partition label of the memory card exists for a long time.
