Simply deleting the data or reformatting the disk does not actually erase the data permanently. It can still be recovered using specialized software. Saving over it may partially overwrite the data but does not guarantee complete erasure. Using a file shredder software is the best choice as it will overwrite the data multiple times to ensure it cannot be recovered.
