I want to make a one-time Time Machine backup of my girlfriend's computer. She has about 800GB of data on her drive, and 1TB free on a 2TB external. Can I safely use that remaining space on the external drive for a backup WITHOUT partitioning it? Will Time Machine keep the files that are already present intact?
Got a tip for us?

Yes, TM will leave the existing files alone. However, the disk must be formatted to HFS+ (with journaling) in order for TM to use it. If the drive isn't formatted HFS+, TM won't touch it.
