I've never used TAILS, but it's a Debian derivative and I have Debian 8 in a virtual-machine. On Debian you have an enabled root account by default, if the same is true of TAILS then you can login to the root account using:
and then entering your root account's password. To get out of root, type:
If Sudo is installed it will show the version number. If you need you can install Sudo (this will require logging in as root) and then add your user to the sudoers list. One reason for using this approach (sudo su) is that when you use su normally you have to enter the password of the user account you're switching to, but if you're using the su command as root you don't. By using "sudo su" you give your user elevated privilidges, which means, like when using root, you won't be prompted to enter the password for the user you're trying to login as, but because you're using Sudo you will have to enter your current user's password.
3. You've listed a file "/dev/sda" (in this case a block-device), but haven't said what to do with it, and it shouldn't be appenended to your root login command either because it will be interpreted as a user account you're trying to switch to. Even if you attach it using & or && the command will be run as your user, not as root.
What exactly are you trying to accomplish?
