How to solve the Win7 computer recognition to the U disk but does not display the drive letter

First of all, we need to check if the USB interface of the computer is available. For example, if you connect your mobile phone to your computer, you can use it normally. If the USB interface of the computer is normal, the reason for this problem is that the system does not assign a disk symbol to the USB disk, so the USB disk cannot be displayed normally. Below, I will explain to you that the Win7 u disk drive letter does not show a solution.
First, enter the "management" menu of "computer". Use the right mouse button "Computer" and select "Manage" to enter the computer management interface.

Second, select Disk Management in Computer Management interface, here, we can clearly see that there is a "Removable" disk. This is the U disk we are looking for. Careful, we can find that the "removable" disk just has no disk disk symbol. Of course, we only need to add the disk disk symbol to the U disk.
Third, select the pocket U disk PE in the interface, right click to change the drive letter and path, as shown below.

Fourth, click the Add button, enter the next step.

Fifth, we can choose a drive letter to it, this is our next drive letter to give U disk drive it is assigned, where we choose G, select Done and click OK.

Six, when we re-open my computer can see the contents of U disk drive and inside.
