Hi, excuse me for being a bit slow PC wise, I'm still learning. I have XP Home. 250 gig HD, and 80 gig external HD for back-up. I also have Acronis True Image 9 and Acronis Disc Director Suite. My problem is backing up to the erxternal HD. I cloned my PC Hard Drive to the external HD, and then later did two Incremental Back -ups. I am now told the external HD is full.(I should mention I have two Partitions). What I am trying to do is copy my Pc to the external HD and keep it up dated so I could set myself up elsewhere, if it became neccessary. I feel I have made a fool of myself and have to start from scratch. Please could someone give a step by step on 1) How to format the External HD removing the partitions (I have two partitions on the PC as well.) and 2) give me a step by step on how to do the Back-up properly. Many thanks. jopras.
