Eject buttons:

 Press down firmly to unseat the drive from the SATA connector 

inside the unit.

Power LED:

 Glows to indicate the unit is powered up.

Disk LED (Disk1 and Disk2):

 Glows to indicate a drive is connected and powered 

up, blinks to indicate activity.

Duplication Progress LEDs:

 When connected to a USB host, these blink in 

unison to indicate I/O activity. With no host connected, they will remain dark until a 

copy operation is started.

Clone Button: 

Press and hold for three seconds to start copying from Disk1 to 

Disk2, when no USB host is connected.

Backup Button:

 Press to launch the HDMU3 backup utility.

Disk Cloning

1. 

Be sure to insert the SOURCE drive into the Disk1 slot and the TARGET drive 

    into the Disk2 slot.

2. 

The TARGET drive must be equal to or greater than the capacity of the 

    SOURCE drive.

3. 

Power up the unit with the SOURCE and TARGET drives inserted and the USB 

    cable disconnected, then wait a few moments for the drives to become ready.

4. 

Press and hold the Clone button for three seconds.

The unit will then blink the Disk1 and Disk2 LEDs to indicate activity, then if no 

errors occur, the Progress LEDs will begin flashing in a back-and-forth pattern, and 

as the process completes past each percentage on an LED, that LED will glow 

steadily and the remaining LEDs will continue the pattern. When all four LEDs are 

glowing steadily, the process is complete.

If there is an error after starting the copy process, all four Progress LEDs will blink 

rapidly in unison, and the LED associated with the drive having a problem will 

remain dark. For example, if the TARGET drive is not equal to or greater than the 

capacity of the SOURCE, holding the Clone button will cause all four Progress 

LEDs to blink rapidly, the Disk1 LED will be glowing, and the Disk2 LED will be 

dark.

Using the One-Touch Backup Feature

The backup utility is provided on CD or download with its own user guide. Once 

installed and the backup settings are in place, pressing the Backup button will 

launch the backup utility from the system tray and begin the backup process 

automatically.
