How to Hide a Partition/Drive

SHARE:

Adjust text size:


Many users want their data to be unavailable to any other person that has access to the same computer. To prevent accessing personal data there are so many ways: simply hide the files and folders, encrypt data, use password protected accounts or move data on a removable media.

As more and more HDD storage is available for every computer, users started to partition their hard disk for a better control and maintenance of the data on it. So more and more partition appeared, each one created for a specific reason: partitions for music, for movies, for the operating system etc.

A good privacy solution would be hiding the partition that holds the incriminatory data. Data that you don't want to be accessible for the curious eyes. But how? Microsoft did not create any option that would enable the user to undertake such task?

There are two methods to hide a drive/partition:



1.Using TweakUI - this method is easier for inexperienced users and requires the installation of Tweak UI, a tweak utility created and delivered for free by Microsoft.
2. The hard way - editing the registry.

Using
TweakUI Tool

Download the utility and install it on your computer. Launch the application and in the left, go to My Computer -> Drives.

A list with all the drives will be displayed in the right. Every drive/partition has a checked sign in front. This means the drive/partition is visible under the Windows Explorer. To hide the desired drive, just uncheck its letter, click Apply and that's all. The drive will become hidden.

Even so, you will still have access to it by typing its letter in the explorer address bar. This is not a high security tweak but it offers protection against the curious eyes.

Editing the registry

In order to hide a drive/partition inside Windows, you can always edit the Registry. Although is not as comfortable as the method presented above, you can do it in a matter of minutes.

Go to Start -> Run and type Regedit to start the registry editor. Now you need to follow a specific key which must be edited:

HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Policies / Explorer

Right click in the right panel and select New->DWORD value. Name it NoDrives. You will immediately observe that this new DWORD value got its data something like this: 0x00000000. The 0x in the front of the value means the number is stored hexadecimal (base 16). There are four sets of double 0. This means that every set has its representations as follows (from right to left):

- first set: drive letters from A to H
- second set: I to P
- third set: Q to X
- fourth set: Y to Z

The value number for the each drive is:

1 for A I Q Y, 2 for B J R Z, 4 for K C S, 8 for D L T, 16 for E M U, 32 for F N V, 64 for G O V and 80 for H P X.

Now focus on the information I provided you with above. If you want to hide partition E:, you should edit the NoDrives value as follows: E: corresponds to the first set of double 00 and the value for E is 16. Therefore, replace the first (rightmost) double 00 with 10 (the hexadecimal representation of the number 16).

Just for extra Information, I don't think you can hide a partition that contains an OS, if you try to do so, it will prevent you to boot that OS. Im not sure if it also happen for the above methods as Im using partition magic.

BTW, thanks for this -- it was JUST what I was looking for, a bit of decimalness aside.

One last thing: You don't say WHICH pair of numbers is the first. On the right? On the left? I'm guessing it's on the right since each entry is little-endian.

Yes, in this case "first" means rightmost. The article has been updated accordingly.

Dear All,

Here is an easy and short way of hiding computer hard drives partitions.


Click the Windows "Start" button. Click "Run." In the command line, type "gpedit.msc" to open the group policy editor.
Step2..Move your mouse down to "User Configuration" and click the " " sign next to it. Click the " " sign next to "Administration Template."
Step3..Browse down to "Windows Components" and click the " " next to it. Click on "Windows Explorer."
Step4..Look for the line that says "Hide these specific drives in my computer" on the right side of the screen. Double-click ""Hide these specific drives in my computer." You can also right-click, then click "Properties."
Step5...Select the box next to "Enabled." Click the arrow next to "Restrict All Drives" and select the drives you want to hide. Click "Apply." Click "OK." Click the red "X" in the top right corner to exit group policy editor.
Step6..Double-click the "My Computer" icon on your desktop to make sure the drive is hidden.
Step7...Check your personal firewall software for errors. If it pops up with a screen asking you to allow registry changes, click "Yes."


Thanks.

Easiest way:System and security>administrative tools>create and format partitions>
right click on the partition you want to hide (dont do for partitions with os)
>>click change drive letter
-You should be provided options to add, change, remove,
>>click on remove --YOUR DONE--

Summary: get to where you change the drive letter and just remove the drive letter instead. Thats how you hide it from view

@Abdul Hadi Sabir

yeah literally it works, "hiding" drives, but somehow it show when you run it in RUN command,

example: when u hide drive D:

>START > RUN > (type D:)

still the contents of drive D: will be shown.

Comment #5.1 by: Ramesh on 15 Sep 2010, 05:14 GMT

hi allansd
really the drive can be hided but it can be accessible by users from run.
In order to restrict access to users even when it is shown can be done by enabling the prevent access to drives in my computer located on same location to hide the drive.

If you want other people to can't access the disk that you are hidden. You must hide it before you boot the OS. So you should try "Gag 4",a boot manager,freeware,to manage your partition before booting the OS.
