Toshiba Hard Drive Erases Itself

Toshiba has just launched launced a new generation.of its SED (Self-Encrypting Drive) hard drives with a new and unique feature. The hard drive automatically deletes its content if moved to an unknown computer or if there is another incident which the user can definere.SED models encrypts all data with 256-bit AES encryption and complies with the "Opal" specification from Trusted Computing Group .

The hard drive can be attached to a single computer with a Trusted Platform Module. If the hard drive so will be removed and placed in a second computer, it will no longer work.

At the same time it is possible to configure the hard disk needs to implement a complete "wipe" the moment an unknown host tries to access the stored data.

It is also possible to set the data must be erased when the hard disk receives a specific command or when power supply is interrupted - so no words are being implemented already in the moment it is taken out of the cabinet.

This can be handy if your hard disk for example. placed in a copier or printer, where it is relatively easy to remove.

Just copiers and printers have long been a security problem. Their disks containing copies of the documents are examined - information that can be read or restored if you get hold of a used unit.

But the automatic erasure helps, of course, not much, if the hard drive built into a laptop, which is then stolen. Here the only security so that the encrypted content on the hard disk is protected with a password.

Toshiba offers various versions of SED hard drive 160-640 GB, 7200 rpm, 16 MB cache. Requiring additional software to exploit the encryption function.

HP, Dell and several other PC companies have already various solutions where you can send a command for example. a stolen PC and get it to erase the hard disk. It works so only if the hard disk still in the original computer and if it is coupled to the network.
