MEDIA 
REDMAG 1.8” SSD
 is available with capacities of 64GB, 128GB, 256GB or 512GB. 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. 
NOTE: When using a RED STATION in conjunction with a 512GG REDMAG, power must be supplied to the 
RED SATAION. It will not function properly using a USB cable as the sole power source.  
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. 
A.
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: 
A.
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 “---“). 
B.
On REDMOTE, NONE will be displayed twice (as opposed to when no media is inserted, the GUI 
displays NONE with three dashes below “---“). 
C.
On the Side Handle, NA will be displayed (same as if no media is present). 
3.
