Explanation
A low-level format (more accurately, a secure erase that overwrites all sectors with zeroes or random data) effectively wipes all data on the drive, making previous content unrecoverable while leaving the drive's structure intact for reuse. Unlike degaussing - which destroys the drive's magnetic media and renders it unusable - overwriting allows the drive to be repurposed safely.
