Install an mSATA drive
Warning! Drives should be handled carefully, especially when they’re transported.
If you’re not careful with your drives, you may lose data as a result. Always handle
storage devices with caution. Make sure that you’re properly grounded by wearing an
anti-static strap when you install any computer component. If an anti-static strap isn’t
available, touch a large grounded metal surface for several seconds to discharge any
built-up static electricity.
Note: The screwdriver provided with the dual-bay enclosure is meant to be used with
the mounting hardware and is too small to be used with the plate screws.
1. If the cover plate is installed, use a Phillips screwdriver (not provided) to remove the
two plate screws located on either side of the enclosure’s USB 3.1 Micro-B port.
Note: The dual-bay enclosure ships unassembled, so you don’t need to remove the
cover plate the rst time that you install a drive.
2. Depending on the length of your drive, you might need to move the preinstalled
mounting screw and stando. Place your drive next to the drive tray and note the
hole that matches the length of your drive. If the mounting screw and stando are
already installed in the correct position, use the provided screwdriver to remove
the mounting screw and proceed to step 5.
3. On the reverse side of the drive tray, use a small set of pliers to remove the nut
holding the mounting screw and stando in place.
4. Place the nut and stando that you removed in the previous step in the hole that
matches the length of your drive and tighten them.
5. Gently slide the connector on your mSATA drive into the corresponding connectors
on the enclosure. The connector on your mSATA drive is keyed so that it only ts
one way.
6. Gently press down on the drive so that it sits ush against the stando.
7. Hold down the drive and use the provided screwdriver to position the mounting
screw that you’d previously removed through the notch on your drive and into the
stando, and tighten the mounting screw to secure your drive in the drive tray.
8. To install a second drive, repeat steps 1 to 7 using the remaining bay.
9. Set a RAID mode. For more information about how to do this, see the “Set a RAID
mode” section.
10. Slide the drive tray back into the enclosure so that the USB 3.1 Micro-B connector
is facing outward and the mounting holes line up.
11. Place the cover plate onto the front of the dual-bay enclosure, and secure the plate
in place by inserting the two plate screws on either side of the USB 3.1 Micro-B
connector.
12. Use a Phillips screwdriver (not provided) to tighten the screws.

Connect a drive to your computer
Note: A USB-A and a USB-C cable are provided with the dual-bay enclosure to
accommodate the type of USB port that your computer is equipped with. When you’re
connecting your computer to the enclosure, make sure that you’re using the cable
that’s appropriate for your computer.
• After you install a drive in the dual-bay enclosure, connect one of the provided
USB cables to the enclosure’s USB 3.1 Micro-B port and to the USB port on your
computer.
When you connect the enclosure to your computer and the OS automatically installs
the necessary software, the drive is accessible as though it’s installed internally in the
system. Before you use the drive, you need to prepare it for use and format it according
to the requirements of your OS.
Note: The enclosure doesn’t require an external power supply, as it receives enough
power through the USB bus that it’s connected to.
Set a RAID mode
To congure a RAID mode, you need to use the RAID mode DIP switches located on
the drive tray.
1. Remove the drive tray from the dual-bay enclosure.
2. Move the RAID mode DIP switches to the correct position for the RAID mode that
you want to set. For more information about the switch positions, see the “RAID
modes” section.
3. Connect one of the included USB cables to the enclosure’s USB Micro-B port and
to the USB port on your computer.
4. Press and hold the RAID set button for 10 seconds or until a drive LED blinks to
indicate that the RAID mode has been reset.
5. Disconnect the USB cable that you connected in step 3 and slide the drive tray
back into the dual-bay enclosure.
6. Replace the cover plate on the dual-bay enclosure, and secure the plate in place by
inserting the two plate screws on either side of the USB 3.1 Micro-B connector.
