There might be situations where you might want to hide hard disk drives in Windows. Although you can do this by registry hacks, not all people are comfortable editing registry files. Also if you mess up editing registry, it could end up with Windows being unstable.
NoDrives Manager is free tool for Windows 7, Windows 8.1 and Windows 10 which allows you to hide hard disk drives. The app hides Windows logical drives by modifying the registry. The hidden drives are still accessible but they are not visible in the Windows Explorer.
The app has a simple interface where you can see all the drive letter listed. Now, all you need is to find the drive letter which you want to hide and check the box against it and save the changes. You will have to log off or restart Windows explorer for the changes to take place.
Once you restart the explorer, the drives will be hidden.
The latest version also comes with option to set password for the drives and the password is encrypted and you will need to enter password to open the drive. If you want to enable the drive, you need to uncheck the box and save it once again.
It is a free and useful utility to hide logical drives in Windows without having to play with registry settings.
