So I'm trying to Encrypt one of my Hard Drives using TrueCrypt.
It says it's in use of by either the operating system or an application, but I cannot figure out what's using my Hard Drive.
I am using Windows 8, and it's not my Boot Drive. I actually have 2 of the same Hard Drives, and one of them I encrypted just fine.
It's very strange since the one I'm trying to encrypt is used the least out of all of them.
Thanks in advance for your help.
