Have you ever forgotten your password for your work laptop and had to go to your IT guy for help to reset it? Imagine if it was that easy when the data on the hard drive was classified or top secret.
Commercial SSDs use basic ATA password to access drive data. Military and government applications require higher security and therefore basic ATA passwords must be strengthened and sophisticated key management techniques employed. Self-encrypting drives allow for up to 32 character passwords while Mercury drives 64 characters. One technique is to condition the password. By this you can create a unique suffix to the end of a password that changes with each log-in, making the password impossible to hack.
