Not only companies have to compliance with privacy laws, individuals shall take private information on the hard drive into consideration too when they made up their mind to recycle used computers.
"Free space" actually made up of two kinds of space: the real free space and the deleted files' space. Take a brand new hard drive for example, all the space can be called free space before it is initialized, if you have downloaded some files to the hard drive and then deleted them, you may found out that some clusters still have deleted files' contents in them, they then cannot be call free space any more, but deleted space instead. With the continued use of the hard drive, real free space becomes less and less and deleted space is gaining its area. By the time you determined to donate the hard drive, it's full of traces of all kinds of information.
