This function test the state of memory, and start the initialisation of the memory.

MORE (see SPC-3 §5.2.4) : The TEST UNIT READY command allows an application client to poll a logical unit until it is ready without the need to allocate space for returned data. The TEST UNIT READY command may be used to check the media status of logical units with removable media.

Parameters:

Returns:
Ctrl_status It is ready -> CTRL_GOOD Memory unplug -> CTRL_NO_PRESENT Not initialize -> CTRL_BUSY
