3. Permanently erase external hard drive with File Erasure


Deleting using your files using your PC or Mac’s system settings doesn’t wipe the files from your computer. Any data recovery software can easily trace and recover the files.

A file erasure software is the prescribed method to permanently delete files from your hard drive. A file erasure software functions by overwriting on top of the files you wish to delete. This overwriting can be done once or multiple times. As a result of the erasure, the files become unreadable and beyond the capacity of a data recovery software.  This is known as erasure beyond recovery and only an efficient file erasure software could accomplish that.
