How do you permanently erase data so that it cannot be recovered?
Permanent file deletion requires intentionally sanitizing data at the storage level so it cannot be recovered later. That means applying data sanitization methods—such as secure overwriting—directly to the data itself, rather than relying on standard deletion or cleanup actions. As mentioned above, files that have been deleted still remain on a computer’s hard drive. The operating system does not know where to locate the file, so it becomes virtually invisible. Sometimes the file’s data remains intact after it’s been deleted, but sometimes it is broken into smaller pieces.In reality, deleting a file doesn’t immediately remove it from your hard drive. Instead, the system just marks that space as available for new data. Until something else takes its place, that file can still be recovered.
