Hi. I get the following message when I try to backup to an external USB hard drive with Acronis True Image Home 11. The backup archive file will be created on the volume of GUID partition table (GPT) disk. Please note that you will not be able to restore this backup archive when booting from the rescue media. Are you sure you want to continue with this procedure? The external harddisk is not present when booting from the "Acronis Rescue Media" but it is when I use "Norton Ghost Recovery CD". Please give me some advise so I can backup with Acronis to this drive because I think Acronis is much better. Any feedback is very much appreciatd.
