FirmwareĪTA Secure Erase is the most common of these a program built into your hard drive that allows you to overwrite the drive via firmware commands. That’s why it’s important to include multiple methods in your data security policy. We’ve outlined some of the best practices below: Methods for Data ErasureĮspecially in the case of SSDs, no one method is guaranteed to erase data completely every time every method comes with some risks. The methodology behind your enterprise data security procedure will be the single greatest defense against malicious data collection once your hard drives are disposed of, destroyed, or recycled. Our previous article on storage devices should help with that, if needed. In order to understand how to properly deal with your storage assets, and implement sufficient enterprise data security procedures, it’s important to first understand generally how they work.
