Question

Quizplus · Accepted Answer

Simply deleting the data or reformatting the disk does not actually erase the data permanently. Saving over it may partially overwrite the data, but fragments of the original data may still be recoverable. Special shredder software is the best choice as it overwrites the data with random patterns multiple times, making it almost impossible to recover any of the original data.
