USB Not Showing Up

Hi, i have an 8GB flash drive. For some reason it doesn't show up in My Computer but it dose in disk management. But there is no partition to format or create It is just called removable and says No Media. Any help would be appreciated. It says its partitioned with MBR . Please help.
 
Right click on the pen drive in disk management of windows and set it to online mode.
You right click on the part where it shows the drive letter assignment and the full capacity of the drive in storage side to the left. then set it to online if it`s grayed out.

Make sure that the pen drive does not share any of the same drive letter assignments already in use by drives connected such as HD`s or SSD drive or DVD rom drives.

If you right click on the drive select change drive letter and select a new drive letter assignment for the pen drive such as :K for example then set the drive as said by right clicking to online mode.
