USE NODRIVES MANAGER TO HIDE PARTITIONS IN A SINGLE CLICK
You probably already know that hiding hard drive partitions
on Windows involves the old school trick, where you edit a couple of registry
keys, and the partition becomes invisible instantly. To get it back simply
revert the changes in the registry.
But why mess with registry when you can do the same thing with this handy
utility, NoDrives Manager.
NoDrives manager is a small and lightweight utility that doesn’t even
require installation. Just download it from this link,
unzip it and double click on the executable file to launch it.
To hide a drive/partition selects it and then click on Hide All
Drives button. To unhide them again, simply do the reverse.
Isn’t this easy 
Enjoy!
