If you’ve deleted files on your main drive, those files are marked as free space by the system and can be written over as needed. It’s important to stop using your computer as soon as possible in this situation. Do not download any software to the drive where the deleted files were (as that download may overwrite those very files you’re trying to recover). There are a few options for you in this situation:
Boot your computer from our Data Rescue Boot DVD If you own Data Rescue 3 and have the Emergency Recovery Boot DVD, simply follow the instructions printed on the DVD — Then run a deleted file scan on your drive — You will need a second drive to recover the deleted files to. If you do not have a Data Rescue Boot DVD, you may purchase one online here: /products/data_rescue_buy.php . It is important that you download the boot DVD image to a different computer, burn it using that other computer and then take the disc to the computer you’re trying to recover deleted files from. Your email receipt for the Boot DVD image download will include instructions on how to burn this boot DVD and use it to boot your Mac. You may also purchase Data Rescue 3 in a retail store (Apple store, MicroCenter,etc) or online store (Other World Computing, Amazon, etc). The retail packaged box will include the bootable DVD inside the box.
Boot your computer via FireWire Target Disc Mode (using another Macintosh) Target Disk Mode Turn off the Mac that has the deleted files you’re trying to recover. Connect another Mac to it using a firewire cable. Boot the secondary Mac as you do normally. Boot the original Mac with the deleted files while holding the “T” key on the keyboard for that Mac. Hold the “T” key until you see a FireWire icon floating across the screen. On your secondary Mac, download and open the Data Rescue 3 demo. In Data Rescue 3, select the Target FireWire connected Hard Drive as the drive to scan.
If you do not have access to another Mac, you may contact our sales department to order a bootable DVD to be shipped to you for $7.50 shipping and handling so you may demo the software prior to purchase. You may call our sales line at 877-477-6763. If the demo works for you, you may then purchase a full license for $99 and do the complete recovery
Boot your computer via secondary bootable drive
If you have a bootable secondary HD that has a Mac operating system on it, you may use it to run Data Rescue 3 & scan your drive. Here’s how:
From a powered off state hold down the “option” key while powering your Mac up. Once the option’s menu appears select your bootable HD and click the arrow to continue. Install Data Rescue 3 to the HD and launch it. Now you can scan you HD safely while booting from another drive. If the deleted files you are trying to recover are NOT on your main drive, then you can simply download the demo for Data Rescue 3 to that main drive, install the application and run it, scanning the other drive where the deleted files occurred.
