As businesses incorporate more technology into their environments, companies will learn that these technologies do not last forever. When storage mediums such as tape or hard drives need replacing, businesses will copy and move the data to a newer drive.
Once copied, many individuals think that merely erasing the storage medium will remove all the data. Erased devices still contain sensitive data, even if you cannot see it on a computer.
Services and programs exist where individuals can recover data from various storage devices. With media sanitization, the devices are wiped and left unusable afterward. Multiple methods can ensure that no data is recoverable depending on how information is stored.
