Self Erasing Hard Drive

Finally, I get to make a blog post which is actually geek related and doesn't contain a Youtube video. Toshiba have made a hard drive which automatically wipes itself when it's put into a different machine.

"The SED performs a cryptographic erase on itself. Unlike a regular erase which overwrites data several times to obliterate it, a crypto erase actually just nukes the crypto keys. Data on the dive is encrypted using a 256-bit AES algorithm, and is unencrypted on the fly during normal use. Once the drive detects that it isn’t in its usual machine, it destroys its keys, making the data impossible to decipher."

Of course, this is good news for people like you and me, when it's placed into a different machine all the data will be permanently encrypted and unreadable.
