I have a 500 GB SimpleTech hard drive (outboard) that I recently discovered to be full. Upon exploring its contents, I discovered MANY backup files and have NO idea how/why they were created. I deleted several of the older files to make room for files I wished to store, and then explored further. On the hard drive, I find one folder named HPLAPTOP01 and another named WindowsImageBackup, between them holding MANY GB worth of files with names: Backup Set yyyy-mm-dd xxxxxx. Is Win 7 creating these backups, or is the SimpleTech drive doing it?
