Some of you may be wondering, 'Could I search the raw data on the disk to see if there are any copies of the data anywhere?' The answer is yes and no. Overwriting the entire disk is the only way to be 100% sure the name is gone. It is safe to assume that even if a file has been securely deleted, its name will probably continue to exist for some time on your computer. It's hard to know how to respond to this problem.

This does not work for SDDs, flash drives, flash sticks, as their disk management stores the file in places which can not be addressed by other tools directly.
