OS X Snow Leopard’s Secure Delete Doesn’t Work With SSDs

OS X’s secure delete, which overwrites data multiple times so snoops can’t recover them even if they have access to your hard drive, turns out to not work with SSDs. The problem? SSD write algorithms are different, because the physical media is different, but also to preserve its lifespan. The end result though is 2/3 of a file can be recoverable. [ZDnet]
