Looking at your Z drive .....in your screen shot, that drive is not activated so to speak, all you did was format it, but if you look at all your other drives in your pic, that WORK ....notice that their are no lines going thru them in your Disk Management screen. Its not an active NTFS partition at the moment. You should download MiniTool Partition Manager and use that Free program to fix your drive.
Much easier than windows disk manager ....just a suggestion. :)
