# Description:
#     This script will perform several checks in order to ensure that
#     mounted partition is working properly.
#     The test performs the following steps:
#    1. Creates a file and saves the file size and checksum value
#    2. Creates a folder on the mounted partition
#    3. Copies the created file on that specific path
#    4. Writes, reads and deletes the copied file
#    5. Deletes the previously created folder
