• Select your disk by typing select disk # where # is the disk number specified by the results of the list disk command above. 
• Now type in the command clean all. 

Press ENTER and wait till the disk is erased in its entirety. It is at this stage that you need to be careful. First, ensure that you have selected the correct disk and entered the command to erase its data. Otherwise, you may erase the data on the wrong drive that you did not want to.
