Toshiba has come up with a new type of self-encrypting hard drive (SED) that can automatically wipe data if it is removed from a paired computer by an attacker.

Available in capacities up to 640GB, the new MKxx61GSYG drive upgrades the capabilities of an identically-named drive announced last December, which launched the company’s family of drives complying with the Trusted Computing Group’s Opal SSC specification.

The latest version adds new features to the mix for OEMs, including the ability to cause either part or all of the drive to become crypto-erased if the drive detects that it is not operating inside a particular PC.

According to Toshiba, this is useful for point-of-sale terminals as well as some laptops to protect against drive data being accessed at the end of a drive's life or while being re-provisioned.
