1. Check Power Mode (code: E5H or 98H): This command checks the power mode.
2. Execute Drive Diagnostic (code: 90H): This command performs the internal diagnostic tests implemented
by the Card.
3. Erase Sector(s) (code: C0H): This command is used to erase data sectors.
4. Format Track (code: 50H): This command writes the desired head and cylinder of the selected drive.
But selected sector data is not exchange. This card excepts a sector buffer of data from the host to follow the
command with same protocol as the Write Sector Command.
