Recover Media on MAC OS X

To recover media on a Mac^® OS X^® operating system, follow the instructions below:

1. Create a folder on your computer where you want to save recovered .R3D files.

   WARNING: Available hard disk space on your computer must be at least the size of the total storage space on the RED^® media being recovered.

   NOTE: In this example, we create a folder on the desktop labeled “RECOVER” for the recovered files. The path for this folder location on your hard drive is “/Users/yourusername/Desktop/RECOVER”.

2. Use the appropriate docking station to connect the RED media to your computer.

3. Open Terminal.

4. Enter diskutil list into the Terminal command prompt line.

5. Press Enter.

   NOTE: Recognized media device(s) appear and are numbered as “disk1”, “disk2”, “disk3”, etc.

6. Determine the source path and disk number for the disk that you want to recover.

7. Open Disk Utility and select Info on the drive to view the disk information.

   NOTE: In this example, the RED media device that we attempt to recover is “disk1”, with a source path of “/dev/disk1”, and thus the disk number is one (1).

8. Enter sudo redundead /dev/rdisk# /destination/path, where:

   • # is the number of the source disk determined in Step 6, which is one (1) in the example /dev/rdisk1

   • /destination/path is the location created in Step 1, such as /User/johnsmith/Desktop/RECOVER

   NOTE: Drag and drop the recovery location folder into the Terminal window instead of manually entering the destination path. The path automatically generates.

   WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files. Double-check your typing when using sudo. Enter man sudo for more information.

   IMPORTANT: Ensure there is a space after “sudo”, “redundead”, and the source path. The space is required for REDUNDEAD to run properly.

   IMPORTANT: Note the “r” in front of the media source disk. It is required for REDUNDEAD to run properly.

9. Ensure that the command, source path, and destination path are entered correctly.

10. Press Enter.

11. Enter your computer password if prompted.

    REDUNDEAD begins to recover files from the media device. This operation may take a while. Files display in the terminal window as they are found and rewritten.

    NOTE: To stop the recovery process, press CTRL+Z. Files that have already been recovered remain. Any files currently processing stop at the current location.

12. Wait for terminal window to display Done! indicating REDUNDEAD is complete.

13. Open the destination folder to verify files that were successfully recovered.

    NOTE: RED recommends that you unmount the drive from Disk Utility before physically removing it from the computer. This helps to prevent unintended corruption of the drive and/or files.
