First and foremost, turn off all power to your computer immediately! If you continue to leave your system running, or try to recover the data yourself, you will lower your chances for a successful recovery significantly. Do not run any software utilities on your computer. Many of these tools will change the structure of the data on your disk and possible cause more damage. Send your media in to a professional who has the tools and proper equipment to ensure a safe recovery. We have seen countless times where people try to recover the data themselves or have a technically inclined friend help, only to cause the drive to become unrecoverable. Please, at least call us first.
