3.  Push down on the Blue Function Button (located 
on the top of the Disk Jockey) one time. This will 
apply power to the hard disk drives and they will 
begin to rotate (spin up). The Power light, located 
on the “Drive 1” side of the Disk Jockey will be 
red. When the Power light turns green the hard 
disk drives should mount to the desktop (Mac) or 
become accessible under My Computer (Windows)  
making them accessible to your computer for 
erasing, partitioning or formatting the drives.
MODE 1 (MIRRORING)
Mode 1 is also referred to as Mirroring. To access this 
mode please switch the Mode Switch to Mode 1 prior to 
powering up the Disk Jockey or the drives. In this mode 
two hard disk drives are attached to the Disk Jockey via the 
Drive1 and Drive2 ports (via the ribbon and power cables). 
The Disk Jockey is then attached directly to your computer 
using either USB 2.0 or FireWire. In Mirroring mode the 
drives are then represented to the computer as one volume, 
HOWEVER, all data that is being written to the volume is 
simultaneously written to both hard disk drives. This mode 
is perfect for keeping a real-time backup. 
NOTE - There is no automatic rebuild of a mirror should 
one drive fail, however, you will immediately have access 
to the remaining hard disk drive and all of the copied data 
should remain intact.
IMPORTANT – Before mirroring two hard disk drives
