APPENDIX B: MANAGING DIGITAL MEDIA  
MEDIA 
REDMAG 1.8” SSD  is available with capacities of 64GB,  128GB  or 256GB. Record duration is 
dependent on resolution, quality and frame rate, but a 64GB SSD will typically provide 24  minutes of 
24fps 5K RAW recording. 
On MAC computers with REDCINE-X PRO installed, RED Watchdog will mount the SSD as “READ-
ONLY” by default and you cannot write the firmware to the SSD. RED Watchdog is identified by the RED 
Coin icon located on the Right side of the Menu Bar. Right-click on the icon to enter RED Watchdog 
settings and change to mount the drive as “READ-WRITE” to allow you to save the firmware to the SSD. 
Refer to REDCINE-X PRO OPERATION GUIDE for complete RED Watchdog instructions and details.  
IMPORTANT: After connecting REDMAG 1.8” SSD to the camera and BEFORE recording, you 
should format the media using the camera (even if formatting  was previously performed on a 
computer). Go to ADANCED MENU > MEDIA > FORMAT to properly format media before 
recording. 
FORMATTING MEDIA 
Media must be formatted prior to using it for recording. Formatting is performed on camera, although 
media may be erased on a Macintosh OS X personal computer, allowing the camera to just add the 
necessary project profile and clip log data. 
NOTE: Media formatted on-camera will use a name and root volume in the format: 
Camera Letter + Reel Number + Month + Day + ** where ** is a two digit alphanumeric random number 
generated by the camera for each file e.g. A001_0512A6.RDM  
Clips recorded to the media follow similar naming conventions 
A001_C001_0512A6_001.RDC and A001_C001_0512A6_H.mov etc. 
IMPORTANT: Media must always be un-mounted prior to removal or disconnection from the 
camera. This ensures power is removed from the digital media and any open data files are closed. 
Failure to do so may result in lost data or corrupted files. Refer to REMOVE MEDIA FROM 
CAMERA (UNMOUNT). 
This procedure outlines the formatting  of REDMAG  1.8”  SSD media using the RED DSMC  camera. 
Formatting the SSD media will take about 10 seconds. 
1.  Insert SSD into camera. 
-  Insert the REDMAG 1.8” SSD with the RED logo facing outward (away from camera body). SSD 
firmly into its slot, but without using excessive force to prevent damage. 
2.  When SSD media is inserted into the camera, the camera will recognize if the media is unformatted: 
-  On LCD, EVF and external monitors, in the media section of the GUI, NONE will be displayed 
twice (as opposed to when no media is inserted, the GUI displays NONE with three dashes 
below “---“).
