I just got a Western Digital Passport Essential external hard drive. I connected it to my iBook G4 and had no problems loading files onto it. However, when I tried to eject it, I kept receiving the same error message that it's still in use and cannot be disconnected. I even went into the Disk Utilities and tried to eject it there, but it says basically the same thing. All of my applications are closed except for my web browser and Finder. How do I eject the drive properly? Thanks for any input or help!
