Your disk is thinking or trying to do something. In morse code -- is 
'm' so -- -- -- -- is mmmmmmm. When you hear the 'h' (four dots) or 
'ph' (.--.----) it's finishing thinking. A typical sesion will be:

mmmmmmmmmmmmmmhhh or mmmmmmmmppppphhhh.

Similar sounds are made by lot of people in the bathroom while 
poping, you may want to investigate perhaps beastie is poping there.
