1) Login as the user that your going to make this change for
2) Open the registry. In Windows XP, click Run and then type regedit and hit ENTER. In Windows Vista, type regedit into Start Search and hit ENTER.
3) Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer in the right side windows create DWORD Value by right click at the blank area New >> DWORD Value and give name NoDrives

-How do I hide other drives?
If Value for Drive :
A = 1 so,
B = A + A = 1 + 1 = 2
C = B + B = 2 + 2 = 4
D = C + C = 4 + 4 = 8
E = D + D = 8 + 8 = 16
F = E + E = 16 + 16 = 32
G = F + F = 32 + 32 = 64
and so on......
-How if I want to hide more than 1 drive, the example is Drive D and F ?
The answer is easy, just add up value D and F, like this D + F = 8 + 32 = 40
