It does. But - of course - the status has to be read back and parsed. 00 returned after "I" command denotes a working volume being "mounted".

P. S. Unless someone replies earlier, I would need a few days (travelling now) to check my stuff at home to answer the questions about status ($90) byte. My bet is that answer to both is "yes" but have to double check the reasons, which I sort of only recall now - so don't take them as true and correct. [*]
