"It doesn't defeat the "safely remove hardware""
I'm unfortunately going to have to be a pedant here. Telling someone that they can just turn off the computer to remove the drive IS specifically defeating the purpose of them trying to use safely remove. The whole purpose of using the safely remove feature is so that you can safely remove the drive while the computer is still on, as processes could otherwise still be accessing it. This option wouldn't have been created by Microsoft if we could just yank drives in all cases while the computer is still on. If the computer is turned off, you will notice that there is no safely remove button, or anything else on the screen, because the computer is off, and you just remove the drive! There is no need to "safely remove" it then. So, telling someone who is inquiring about safely remove to just turn off the computer to remove the drive isn't helpful at solving their issue at all, because if they had wanted to do that, they wouldn't have posted a question here about how to get safely remove to work; they would have just turned the computer off and removed the drive! I apologize if the OP really didn't know that they could just turn the computer off, but given the fact that they know about Process Explorer would hopefully provide evidence that they aren't a complete novice and are simply trying to remove the drive WITHOUT turning off the computer.
