Hi, new member here. After a hard disk failure (disaster no backups) I upgraded to a 500GB disk and bought a 1T external hard disk. I received PHDM in magazine so trying it for the first time. Questions please: 1. Can I partition my 500GB C drive without losing data? 2. Should I partition my 1T external hard drive before making a copy of C drive to be put on it? 3. Confused by "incremental - differential" choices for backup. 4. Where should I keep the backup - in the same partition as the copy of C disk on the external hard drive or in the other partition on the hard drive. Really appreciate any help. Paragons help file sadly lacking step by step instructions I can understand with confidence.
