How to protect hard disk?

Question

I have 320 GB hard disk on my laptop and I have installed Ubuntu 11.04 on 1 partition and another partition is reserved for storage. I want to protect that storage partition with a password. How can I do that?

Answer 1

TrueCrypt

Package in Natty

From the website: Free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux. Some of the main Features:

• Creates a virtual encrypted disk within a file and mounts it as a real disk.
• Encrypts an entire partition or storage device such as USB flash drive or hard drive.

• Encryption is automatic, real-time and transparent.

  More information about the features of TrueCrypt can be found in the documentation.

And to finish it off a nice (term used loosly...) youtube video on using truecrypt in Ubuntu 11.04

Answer 2

when you're creating new partition trough system -> administration -> disk utility, you can set "encrypt whole partition". Then, always when you will try to mount it, it will ask you for password.

you can backup your data somewhere else, create encrypted partition and put them back
