Hi friends this is a interesting tricks,how to hide the drives from other person.
For this,firstly go to "Run" and type "Regedit" and follow the path
Now in the right panel create a new "DWORD" item and name it NoDrives(it is case sensitive). Now modify it’s value and set it to 3FFFFFF (Hexadecimal) .Now restart your computer. So, now when you click on My Computer, no drives will be shown(all gone…). To enable display of drives in My Computer, simply delete this DWORD item that you created.Again restart your computer.You will now see all the drives again.
