I did not follow the directions here:

and simply erased the filed from Finder.

Time Machine still thinks it's full!

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

You might want to consider erasing the external hard drive with Disk Utility, accessible from Application -> Utilities. Click on the drive you want to erase and select "Erase". Make sure to choose "Mac OS Extended (Journaled)" as the format. After that process, the system will prompt you a message asking you to use the disk as Time Machine.
