Hide a Drive in Vista

There are several reasons you may want to hide a drive in vista... for example if you have a nosy little brother who you need to keep away from your important files. When I say hide a drive what I mean is that you won't be able to see it when you go to My Computer but that you will still be able to access it if you type in the drives location and programs will still be able to use the drive. To hide a drive in Vista start regedit.exe and then go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer. Now right-click on some of the white empty space and select new 32-bit DWORD and call it NoDrives. Next, in the Value data field enter in the number that corresponds to the drive you want to hide (see chart below).

Drive Letter	Decimal	Hex
A	1	1
B	2	2
C	4	4
D	8	8
E	16	10
F	32	20
G	64	40
H	128	80

Finally restart your computer and now the drive you selected will be hidden from view. Note: to undo this tip just delete the NoDrives registry key and your computer will be back to normal.

Other method:

With this tip you can hide a drive from Explorer while at the same time not causing any problems because all your computer programs can access the drive like normal. This can come in handy if you don’t want people browsing the contents of your computer hard drive or if you have annoying siblings who delete your files. To hide a drive first click Start | Run and then type Regedit. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Policies\Explorer. Next, find or create a DWORD value named NoDrives. Double-click NoDrives, and in the Edit DWORD Value dialog box, select Decimal. In the Value data box, type the value that matches the drive you want to make hidden and hit OK. for A: 1; B: 2; C: 4; D: 8; E: 16; F: 32; G: 64; H: 128; I: 256; J: 512; To hide more than one drive add the drives numbers together and then type the new number into the Value data box. If you want to hide all the drives type 67108863. Finally restart your computer to see the change(s).
