I mentioned low level format earlier, I was just referring to the choice of "quick format" or "format and lose all files" that comes up when installing windows XP. I can format and lose all files and reinstall and have everything up and running in 3-4 hours. I keep a folder on the D drive with installation files. After that I tweak things as the need arises, it works out ok.
I used Norton before, it keeps records of restore points but you can't tell what was done to cause the restore point to be set, you have to keep your own record, one more frigging thing to think about... if Acronis tells you what the setpoint was about or even had a space for a description I would use it. I don't recall that Norton had that at all... most people recommend Acronis on ET.
