Peter is correct. Even an amateur like myself can download and run an
application like WinHex.exe. With this, I can read any sector on the hard
disk, whether it has been deleted or not - whether it is or ever was in any
file or not. Even most re-formats leave much readable data behind. If it
has been overwritten - not just deleted - my chances are much less.
There are applications to examine even overwritten data, but they are not
generally available to us amateurs. So a "shredder" application should
suffice for most purposes. Just be sure that it overwrites ALL THE DISK,
not just current or deleted files. Some of the juiciest tidbits might be in
the "slack space" at the end of a long file that has been only partially
overwritten by a shorter file.
Physical destruction of the disk platter(s) is the only sure way. A
whole-disk shredder will suffice for most purposes.
