Tip
(Quick Format VS Full Format) 
The quick format will not really erase all data, which marks the partition as formatted and delete the journal file. So the data is still on the hard drive. If you face the wrong operation, the data recovery software is ready.
However, the Full Format will completely clear data. No chance to recover data.
