Warning!

 Drives should be handled carefully, especially when they’re 

transported. If you’re not careful with your drive, you may lose data 

as a result. 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.

1.  Connect a 2.5 in. or 3.5 in. SATA SSD or HDD to the 

SATA 

connector

 on the adapter.

2.  Connect the universal power adapter to the 

Power adapter 

port 

on the adapter and an electrical outlet.

Note:

 You can use most 2.5 in. drives without connecting the 

universal power adapter, as enough power is provided through the 

USB connection.

3.  Connect the integrated USB 3.1 connector to an available USB 

port on your computer.

About driver installation

After you connect the adapter to your computer, the computer 

detects the adapter and automatically installs the driver. You don’t 

need to take any further action to install the driver.

the adapter, it appears under
