 Following the table below, enter the decimal number corresponding to the drive(s) you want to hide as NoDrives value data. When you right-click on NoDrives and choose Modify, make sure you select Decimal base, not Hexadecimal.

A: 1
B: 2
C: 4
D: 8
E: 16
F: 32
G: 64
H: 128
I: 256
J: 512

W: 4194304
X: 8388608
Y: 16777216
Z: 33554432
All drives 67108863

If you want to hide more than one drive, you simply add the drive amounts together for a combined total.

For example, to hide the D:/ and T:/ drives, add the decimal value for the D:/ drive to the decimal value to the T:/ drive.

8 (D) + 524288 (T) = 524296
To disable all of your visible drives, set the value to 67108863
 Note : if u u must Either  close  explorer ( taskmanger) close explorer and reopen it ( run -explorer) or restart the machine
 again

nOOOOOOOOOOOOOOOOOOOTE
 WHEN U MODIFES THE VALUE  REMBER THERE ARE TWO OPITION
 (decimal-hexadeicmal)
 u  but the  value to decimal
not hexadecimal
ok
 to hide the C and D:  adnd E:   value of decimal must be 4+8+16=28
to hide the C: and D: and  E: and F: value of the decimal must be 4+8+16+32=60
other example
 cut and paste this in  txt file and rename it with extention *.reg
from here-----------------

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

till here ---------------

------- here  dowrd value is hexadecimal   1c= 28  in decimal which u ll write

it will  nt allow  the enter of drive C: and D: and E:
 any othe rthing u wanat im in ur service
if u have 4 drive C: D: E: F:
the value in decimal ith be  4+8+16+32 =60_________ hexdecimal will be 3c
if u have 5 drives C: D: E: F: G:
