I have Paragon Hard Disk Manager 14 Suite and I am trying to backup hard disk (Main hard disk) which has three separate partions C:, Recovery, and Dell utilities partition E: on another disk (Seagate Free Agent disk) which has paritions E: and F: which F: already has files. When I click Copy Hard Disk I select Main hard disk and click exclude masks which I select the option Files that contains your e-mail data then click next which I says source hard disk has OEM partition which is self explanatory then I click next and I select the Seagate Free Agent Disk which has partitions E: which has nothing and F: that has files. I don't want to lose the files from F: which I would like to copy all of Main hard disk to partition E: on the Seagate Free Agent Disk without losing information on partition F: on the Seagate Free Agent Disk. Is there a way to do that, or its better to get another external hard drive and save the files on partition F: and completely clone Main hard disk to Seagate hard disk?
