Browse Source 
the BPartition pointer in _UpdateMenus() was toast after calling
  CancelModifications() on the disk. Most importantly, the Mount/Unmount
  items are now correctly enabled/disabled. And you can no longer initialize
  mounted partitions...
* Added some debug output to help track down why BDiskDeviceRoster
  notifications don't work anymore. I am pretty sure those did work at one
  time.

+alphabranch.
