I test the example of usbd_msc on nRF52840 Preview DK, but only get three empty devices on PC. Where can I get more information about it?

Add some information: my computer runs WIN7, 64bit
Have you tried to follow the instruction here: infocenter.nordicsemi.com/.../usbd_msc_example.html ?
Yes, I had read that instruction, the difference is my pc run win7 not Unix only.
When I connect the USB device port, I can see enumerate three disk, but its empty(size is zero).
About the SDK, I used nRF5_SDK_14.0.0_3bcc1f7.
I also saw 3 empty devices on PC and that what's expected. You then can connect UART and follow the instruction there to format, create a random file , print the folder tree etc. The instruction is in the page. Connect the board again to USB and you should be able to see the files.
Are you sure you can see three devices on PC?why there is None at my PC(win7) when I do according to infocenter.nordicsemi.com/index.jsp you tell me how did you operated?
