write protect in c or d drive

how to write protect c or d drive that no boday can save data in hard disk or no body can copy data from hard disk .....

 

You can set the Read Only property on some Folders, but that
will give you more problems than you have now.
There are some password protected apps on the net that
will immobilse your PC when you are not there.
You can also set a Bios password to complete a boot - I do not
recommend forgetting it tho'
