How To Lock/hide your drives using Mountvol.exe

First of all, if you are a newbie then please don’t try this on your PC or keep a backup CD ready. This trick is for those who understands the consequences and have some experience with computers. You may end up corrupting your current operating system.

This trick works with almost all latest versions of Windows OS’s.

• Go to Start->Run->cmd and press Enter.
• Type mountvol in cmd and press enter.
• Now you can see all the drives in your system with the corresponding ID’s.

• Now suppose you want to hide your G: drive, note down the volume id for that drive. In my case for G: drive the volume id is \\?\Volume{96c924d1-7f19-11de-808a-806e6f6e6963}\.

          This step is very important. If you don’t note down your volume id you will not be able to get your partition back.

• Now the final step to hide your drive. Type mountvol G: /d to hide the G: drive.
• To get your hidden drive back type mountvol g: [volume id]. For me it is \\?\Volume{96c924d1-7f19-11de-808a-806e6f6e6963}\. SO it will look something like mountvol g: \\?\Volume{96c924d1-7f19-11de-808a-806e6f6e6963}\
• Be very careful while performing this trick. I am not responsible for any kind of loss.
• Most important:Never try to hide your System Drive(The drive in which your OS is loaded). You may screwup your PC. So use it wisely.
