Self-encrypting drives are hardly new, but that doesn't mean researchers aren't still looking for ways to give those IT folks behind the curtain more ways to lock down sensitive intel. Toshiba just launched a line of self-encrypting HDDs that will "invalidate" the data -- essentially, rendering it useless -- when the laptop connects to an unknown host. IT departments can also use Toshiba's so-called Wipe Technology to scrub a machine before tossing it, or encrypt the drives every time someone powers down. The company won't be peddling these directly to consumers, of course, and in fact, Tosh is planning on shopping them around not just for laptops, but multifunction printers and point-of-sale systems, too. They'll come in five sizes, ranging from 160GB to 640GB, and will all run at 7,200RPM. And Tosh says it'll work with OEMs to help them customize the conditions that will trigger a data lockup. It's too soon to say what laptops will pack this technology, though the company is clearly moving quickly -- it'll start showing off samples this month and will ramp up mass production by late June.
