This method can be used only on Windows XP Professional Edition.

1.Open the Group Policy Editor (Start > Run, type in “gpedit.msc” and press [Enter]).
2.Go to User Configuration > Administrative Templates> Windows Components > WindowsExplorer.
3.Here, you’ll find “Hide these specified drives in My Computer” and “Prevent access to drives from My Computer”.
4.The difference between the two settings is that “Prevent access” will allow the user to see the drive icon, but will give an error message when he tries to access it.
5.“Hide” will remove the icon so the user won’t see it, but the drive can still be accessed by using Start > Run and keying in the drive letter.
6.Under this setting, after you click the radio button next to “Enable”, you’ll see several options. Choose the one you want to
apply, for example, “Restrict A and B drivesonly”. You’ll notice that the options here are restricted; you cannot, for example,
choose to restrict drives A, B and D.

Very nice tutorial !
Now I know how to hide my secret documents so that my boss cannot see them if he happens to power up my computer when I'm not there !
Of course, I guess that this is a trick all real hackers know, so my data are not really protected. But this is a really noce tutorial, because unexperienced people (like I am) are anable to know that my D drive exist, they will simply open Windows Explorer and they will see that I only have my "standard" c: disk, with nothing special in it.
Really nice !
I will try this next time I will go out on holidays, I will hide my D disk and see if my collegues will continuye spying my PC.

the tutorial is very nice for hiding stuff,but just a tip you can even use folder lock for locking files it is really good as none of your files appear in search results ,they dont even show the files ,even if show hidden files option is enabled ,the software could not be unstalled when the whole thing is locked,so no way someone could grab the data by uninstalling,thay say that even when you uninstall the operating system or change it ,or upgrade it ,then also no way the data gets accesible its completely lockes and nothing happens to the software folder lock .the main thing is that it locks the data not on system level but on a very deep level actually even below the kernel level of your pc and i have been testing it for a long time,there is no way someone grab your data if u use it.check it out ,its flexible and easy ,but not free , could br available free if you go to phazeddl.com hehe but then it will be taking hacking secure software from hackers

hmm... I don't know if this "tip" is helpful for many people, but nice tip, I'll save this for later.

If you really want to hide things, take a look at TrueCrypt. TrueCrypt lets you have an encrypted container either as a whole volume or just a file on the hard disk that will work as a virtual, encrypted disk that is completely inaccessible once unmounted.

For Windows XP Home Edition, you can use the partition tool in Administrative Tools to hide a partition (which is a drive).
Or use Super FDISK and hide your partitions in a different method than Windows does.

I guess I don't really have the need to hide partitions. You may need to when installing new operating systems and stuff. Or just to hide your files from others

encryped volumes
To Hide A Drive From Appearing In Windows Explorer

I use TrueCrypt for some time now. I used other crypting software but I can say that TrueCrypt is by far the best thing for hiding files. It has lots of very useful options including command line operations on volumes which in my opinion is great for developers and not only.
