“After copying all data from my old hard disk drive to a larger disk, I intend to wipe all data from it completely before I give it to my friend. I know that formatting or deleting a partition just makes the data saved on the disk disappears seemingly and the deleted files can be easily recovered if someone uses certain file recovery software. I have ever realized that filing hard drive with random data is a useful way to prevent deleted data from retrieving. But I have no idea how to do it. Is there anyone who can give a detailed process? Thanks in advance!”
