How do I stop external USB hard drive from being accessed?

I would like to keep my external USB hard drive plugged into my computer at all times to make backups easy. However, I have noticed that the computer likes to access the USB hard drive automatically at certain times and that causes slowdowns. I do not want any slowdowns at all while playing games or using other applications. Therefore, how do I completely stop my computer from accessing my external USB hard drive while it is plugged in, and how do I access the external hard drive only when I want to and stop all access to it (and resulting slowdown) when I don't want to access it?

By the way, I am using Windows 7 Professional 64-bit operating system.

Any responses will be appreciated.

Thank you very much.
