A company is transitioning to solid-state drives and needs to securely prepare their existing mechanical hard drives for donation. To ensure data cannot be retrieved by third parties but still provide functional drives to the recipients, what process should be followed?
Fill the drives with dummy data files until the storage is full, then format the drives.
Dismantle the drives and manually scratch the magnetic platters before the donation.
Run a software-based data sanitization tool on the drives to overwrite existing data with random patterns.
Perform a quick format and encrypt the remaining data on each drive to prevent easy access.
