Hi Bev,
Have you treble-checked :-). I'm pretty sure one of those 399 rows must have a value of 2 (active). As soon as you create a database, some info gets written to its log file and one of the VLFs will be active.
USE master;
go
CREATE DATABASE NewTest;
USE NewTest;
go
DBCC LogInfo;
As for space resue - this does require a log backup if the database is in FULL recovery model, but not in SIMPLE.
