The edges of the vl711fo main control chip hard drive box are rounded, which can be seen that the workmanship is really good.
At the top is the Usb3.0 Micro B interface, and to the right is a blue LED indicator.
Also open from the back, press and slide to remove, there are also protective sponges on both sides of the hard disk bit.
However, when the bottom of the back cover is not connected to the computer, the blue indicator will also blink regularly as the read and write.
