Deleting items in your project just so you can unmount a drive? That makes no sense to me.

You must make sure FCP is not referring to any files on the drive you're trying to dismount. Close the project file, making sure no active applications have files from that drive open. Then you should be able to dismount the drive. However, if you're copying large amounts of data while your project is open, with the data being from the same location as the project file, is a pretty dangerous thing to do.
Are you editing simultaneously? If so, you should just make sure both of you have the exact same set of media and only move project files back and forth. If you're just creating new media, for example effects and music, you shouldn't use the same project file you are using for the primary editing -- start a new project file with the same specs as the main one, then copy and paste the Browser items back and forth.
