How to put password on c drive

[Tee Why L E Are]

Is there any way that I can make my C drive password protected without actually hiding the drive when I go to "Computer?"

I don't want the drive to be hidden, I just want a password to be required to access my C drive.

I'm running Windows 7 Home Premium

All help will be appreciated.

Use TRUE CRYPT or FOLDERLOCK.
