In Windows 7 versions other than Home,it is possible to do a lot of stuff using the good old group policy console (gpedit.msc)
It is possible to completely hide drives from Windows explorer based on how settings are configured in local group policy editor.
Suppose in this example D: drive needs to be hidden.
(It is still possible to access the hidden drives through disk management/command prompt or run the programs residing on that drive,what the setting I will show simply hides the icon of specified drive from Windows Explorer.)
Open Group Policy editor (Start > Run > gpedit.msc) or just type gpedit.msc in search box of Start menu.
Drill down to User Configuration > Administrative Templates > Windows Components > Windows Explorer.
Select the policy – Hide these specified drives in My Computer.
Select the required drives by selecting the Enable option and then the D: drive in this case from drop down box.
Click Ok to save the changes.
To check if drive is hidden,go to My Computer,the specified drive will no longer be visible.
To revert back the changes,select the policy and choose Disabled option.
All drives will be visible again.
Happy drive hide and seeking.
