hide partitions of hard disk

want to hide any partition of your hard disk just follow these  
simple steps.

1. Goto Start > Run and type diskpart



A DOS window will appear with following description

DISKPART>

2. Then type list volume

All partitions will be listed, there will be also a volume number  
for each partitions

3. Suppose you want to hide drive E:, type select volume 3 (Here 3  
is the volume number of E:, in your pc it may vary). A message  
will now appear in the window saing "Volume 3 is the selected  
volume".

4. Now type remove letter E . You may have to reboot the computer.  
Diskpart will remove the letter. Since Windows XP doesn't have the  
capability to identify the unknown volume, it won't display or  
show results from it. To access the content of the hidden drive,  
repeat the process, but in the foruth step, replace remove to  
assign, ie., assign letter E
