5. Right Click on the volume and Change Drive Letter and Paths
6. Click and assign drive letter
7. Open Command line (CMD)
8. type 'diskpart'
9. type 'list vol'
10. find your volume by drive letter
11. 
12. type 'select vol #' (replace # with Volume number)
13. type 'attrib vol clear readonly' (Allows disk to)
14. 
15. Go back to disk management and right click on the volume and Change Drive Letter and Paths
16. Click Remove on the drive letter and Click OK
17. right click on the volume and Change Drive Letter and Paths
