Hi I have question about my external hard drive .. I use my Norton virus protection to back up my computer …but how can I tell if it worked…can just hook the drive to a new computer then open the files ? I just want to see that it really saving my files
You have to have Norton installed to be able to verify the backup happened. Your BEST option is to check the backup using another computer that has the same version of Norton Ghost Installed. You second best option is to use you compute to try to navigate through the files… You should be able to double click the Norton Backup file and navigate thorugh it just like it was another hard drive… And of course you can just check the logs…
