password to be asked

[bipinbaglung]

firstly it used to ask password to authenticate the drive.
But i have made to remember password and auto authenticate the drive. Then it do so.
Now i want it to ask password for authentication at every time it mount the drive. How can i change it?

Several of the distributions now contain a way to encrypt a hard disk so that it can't be mounted until you put in a password, it really depends on what OS your using. More information about the software installed, like OS, kernel version, etc. would be helpful.
