This message will self-destruct in 5...4....3...

If you are old enough, you remember that familiar line from Mission Impossbile.  Well, it is coming to your computer hard drive sometime in the near future.  Toshiba has announced the creation of self-destructing hard drives.  The way it works is if the hard drive detects that it is present in an unfamiliar computer (ie.  stolen computer, thief takes the hard drive out and installs it in another pc or hard drive enclosure), the drive will detect it and either deletes all data on it or locks down the data forever that is on it.  Pretty cool and helpful for all those government agencies and corporations that keep losing laptops with valuable information on it.
