Streakyhair- Sorry to hear about your problem! I was having major issues with Norton Ghost too, so I no longer use it!! First off, where were you having it backup to? It's possible that it dumped some of your files onto your disk, filling it up.. Now that you've uninstalled it, you may want to try Revo Uninstaller, which is free! It will go through and clean up all the files that a program dumps onto your machine, including the registry. Another one you could try to clean up your machine is TuneUp Utilities, although it's not free.. Hope that helps.
