- Enabled the command queueing (in DiskClassCreateDeviceObject).

Browse source 
- Do always reread the partition table in DiskBuildPartitionTable,
  because DiskBuildPartitionTable is only called for removable media's.
- If there is no partition table available, set the disk data entries
  for this volume to the super floppy format (in DiskBuildPartitionTable).
