v10, Windows XP-home-sp2, external USB2 Maxtor drive, NTFS format HD and external. In order to learn more, I tried doing an image running the Recovery CD in full mode. The backup destination was a USB drive. It worked. It validated. It restored, so no complaints, but ... - The resulting file size under Normal compression is 11.5 gig. The backup took 50 minutes, 20 to verify. - Day before, I did a normal image to the same drive, but from Windows. Size was then slightly under 11.5gig. The backup took 18 minutes, 11 to verify. How come I see this substantial time difference?
