I just purchased Acronis True Image 11. On my HP Pavilion laptop I was able to get a backup made but then it showed errors when I validated it. Is these an issue with laptops that make them harder than desktops to use this software? Does the size of the external drive make a difference? I defragged and used Check disk on both my laptop and my external. I reinstalled Acronis twice with no improvement. Ideas welcome. I did send a file to the tech help. Not sure if it actually got through or not with the file attached.
