Default [Q] Access Internal Storage on "cracked" phones...

I have two phones:
  • A Droid Razr MAXX HD
  • A Samsung Note 2 (I believe)

In both cases the phones have cracked screens but appear to still be "running" as their indicator lights still light, I still hear occasional chimes from them and the alarms still go off in the morning. However, when I plug them into my PC, the OS recognizes the devices, but does not show the internal storage anymore. I am not sure if I need to go back into the phone and enable it, but I would very much like to retrieve data from both phones. Is there some sort of special software I can use to enter the console or shell of the phone?
