![]() You’ll want to instruct the computer to overwrite all the bits that made up those files, so they can’t be reconstructed later.įirst off, if you’re using a Seagate Self-Encrypting Drive (SED), it already has Seagate Instant Secure Erase (ISE) built-in, designed to protect data on hard drives by instantly resetting the drive back to factory settings and changing the encryption key so that any data remaining on the drive is cryptographically erased.

Sometimes you don’t want files to be recoverable But those data bits are still on the hard disk, and that means in many cases, those files can be recovered - and it’s not hard to do so, with the right software tools.
