You can hide the "H" in the
Computer Management _Disk Management section.
Right click on "
H"
In the "
Change Drive Letter and Paths" window, click on the
Remove button.
You will be asked to confirm the removal of the drive letter. Click Yes.
Note:
If there are open applications using files from the partition, you are warned that the drive is in use.
But you can also examine what you may have in the context menu, and mually remove or add to it. You will find it here:
C:\Users\Username\AppData\Roaming\Microsoft\Windows\SendTo
The small utility does this manually. I have enclosed a screen shot of the open program, where you can see for yourself what may be available.
