Norton 360 (v3.5.2.11) shows my external drive (500 GB) as too full to run backup.
When I view my backup set, it shows 203.2GB and 41,126 files to be backed up.
However, when I look at the external drive in My Computer, the N360_Backup folder reflects 464GB and 11,063 files.
Norton 360 Backup indicates I only have one backup up set.
What could cause this problem?
