Quick Start Guide

Dual-Bay Dock

1. Flip the switches to set the mode.

2. Insert 2.5” or 3.5” SATA drives into the dock. 

One or two drives can be accessed in JBOD mode. RAID 0 and RAID 1 require two identical drives 

(same model and capacity) for optimum performance. JBOD and Spanning can use any combina-

tion of drives.

Caution

: When using hard drives in the dock after being previously setup, make sure the mode of the dock is set to the same 

mode of the hard drive as when the drives were initially set up. Insert the drives in the same order and same bay as during the 

initial setup. Switching modes or bays might result in data loss. 

For example, if a pair of hard drives was initially set up as RAID 0, make sure the dock is in RAID 0 mode before inserting the 

hard drives again. Also, if a particular drive was in Bay-1 during the initial setup, Bay-1 must be used again for this particular 

drive and vice versa.

*Due to operating system limitations, Windows XP (32-bit )can only access up to 2TB, even if the actual total 

capacity is greater. These switch configurations will allow the computer to access up to 2TB on drives or 

combinations of drives with a usable capacity greater than 2TB.  DO NOT insert hard drives if the existing data totals 

more than 2TB as Windows XP might overwrite or delete it.

Note

: Depending on the 

drives used, when 

powering on, allow up to 

30 seconds for both drives 

to spin up to speed.

Note

: Ensure a proper connection 

when inserting a drive by putting it 

straight down and not tilting it. If a 

drive is not being detected, turn off 

the dock then remove and re-insert 

the drive.

3. Connect the USB and power cables then turn the dock on with the power button.  Wait until 

your computer detects the dock then begin transferring files.  New hard drives need to be 

initialized and formatted. 

Caution

: Removing the hard drives from the dock while it is on may result in data loss. Before turning off the dock, make 

sure the hard drives are not busy as indicated by the solid green “Hard Disk Access” lights on the front of the dock.

 

Accesses the two hard drives separately as “Just a Bunch Of Disks” so that two individual drives will 

appear on the computer. Use this mode if accessing single drives. Usable capacity is the sum of the 

drives.

Increases data transfer speeds as both drives are used simultaneously. A single file is “striped” or 

split up and written across both drives. Both drives will be displayed as a single unit on the 

computer. Usable capacity is the sum of the drives.

Clones or “mirrors” the same data onto both drives simultaneously so only half the total capacity of 

both drives are utilized. If one drive should fail, the surviving drive will have a backup of the data 

from the failed drive. The usable capacity is half the sum of the drives.

Combines the capacity of both drives, similar to RAID 0, but instead fills up one disk first before 

filling the second disk.  Usable capacity is the sum of the drives.

 

If the dock is disconnected from the computer or the computer is turned off, only 1 green light will 

be on and the drives are spun down. In order for the dock to be active, it needs to be connected to 

a running computer.

 

If both hard drives are already mirrored with the same data, then both LED lights will be a steady 

green. When data is being transferred to the drives, then both the lights will flicker.

If one drive is the source (original) drive, and the other is incomplete (different or missing files from 

the source drive), then the dock will attempt to rebuild the second incomplete drive. A blinking 

green light indicates which drive is the source drive during synchronization. A blinking red light 

indicates which drive is the incomplete drive during synchronization. When the dock finishes 

synchronizing (now mirrored), then both lights should stop blinking and stay a steady green. 

 

With only one drive inserted, it becomes the source drive when the dock is turned on. At this point, 

without a second drive inserted, the light for the inserted drive will stay a steady green. The other 

slot will have a blinking red light, indicating there is no drive inserted.

Make sure the power is on and the SATA hard drives have been inserted straight in and not tilted. 

Also check all the connection points as well as the USB ports on the computer as they may be 

defective. 

When one of the drives in RAID 1 fails, you can either (A) switch the dock to JBOD mode to recover 

the data from the surviving drive or (B) insert a new identical hard drive (same model and capacity) 

into the other bay and it will automatically be rebuilt from the data located on the surviving drive. 

Option B is recommended and will allow you to always have two copies of the data. Do not power 

off the dock until rebuilding has been complete. 

Hard drives that have not been initialized may not show up on the computer. Go to Disk 

Management (Windows) or Disk Utility (Mac) and follow the instructions to initialize and/or format 

the hard drives.
