Is it possible to access to the files from a hard disk connected as external? I mean, without logging in.
Im scared about someone at work to take out the hard disk from my computer, then make a copy, and see the files inside my hard-disk.

Yes.
If you have physical access, then you own the computer. Full encryption is the only option to prevent that - and that includes denying you access if the key goes missing.
Otherwise, you just mount the drive (or it's image) in a PC where you are root...
Having physical access to an unencrypted hard drive definitely allows an attacker to gain access to your files. So the best way to protect your data is to use full disk encryption. If your hard drive support drive locking , you can enable that. You can read a little bit about it here: https://security.stackexchange.com/a/33419
There's also another way to steal the data,even without removing the hard drive. Booting LiveCD and chroot
ing the system, allows the attacker to manipulate your data even without removing it from the machine - just takes physical access to it.
