In support of ifixit mind-set, though, it would sure seem preferable to WIPE your drives with an appropriate utility (DBAN (http://www.dban.org/) comes to mind), and then donate them to a re-use center, who could very well have great need for your drives. I know that doesn't answer your specific question (which is over 2 yrs old anyway at this point), but felt that the wipe-and-donate option should be mentioned here, at the very least.
