Right-click on the task bar and under toolbars turn off the one that doesn't work. Then delete the folder where your drive letter is stored. Create a new folder. Put the drive shortcut inside. Set the icon of the shortcut. Next right-click in an empty spot in the task bar and select toolbar ... new toolbar. Type in the address of the drive folder and hit the "select folder" button. There will be little dots ... right-click on them and unselect text. Drag the dots till the drive icon is seen.
This is exactly as described above.
