HIDING ANY DRIVE

01. Go To Start –> Run or use Win+R keys and type this and press Ok

cmd

For Vista/Windows 7

02. This will open Command Prompt for you. Now type below text and press Enter:

diskpart

Note: In Window Vista and higher you will get a security warning, bypass it clicking on allowing.

Once in Diskpart type below text and press Enter:

list volume

This will list all the partitions. Now as in my example I want to Hide Partition G: and it has Volume no. 10. So my next command will be:

select volume 10

Remember to change 10 with the volume number of your partition you want to hide and press Enter:

03. Now as in my example I am hiding drive G: so my last command will be below and then pressEnter:

remove letter G

All done. Now open your computer and see that drive is made hidden:

Now to make a drive Unhidden

Follow first 2 steps as such but in step 3 instead of remove letter G use below command:

assign letter G

For Vista/Windows 7
The commands becomes slightly different here:

assign letter=G

You have successfully unlocked the Hidden Drive.
