How do I safely remove an external hard drive?

I installed "Elementary OS" this morning. When I finished restoring my files from my external hard drive, I right-clicked it to safely remove the drive. However, there was no option to do so. There was only an option, which really does not turn off the hard drive. In my experience, removing the external hard drive with the light still on corrupts the hard drive/NTFS, making it unusable unless I use a Windows computer to fix it. Is there a way to completely and safely remove the hard drive (not just unmounting)? Can I add an option to Files, or can I use the terminal to safely remove it?

I do not speak English, copy the description of the problem from another forum: http://forums.linuxmint.com/viewtopic.php?f=49&t=118171

but is the same problem.
