Hard Drive Image

[edtost]

My school is pushing Win XP SP2 on us in a couple of weeks, and I'm worried about breaking any programs/drivers/etc, since I have no way of reinstalling a bunch of them. Is there any easy way to make an image of my hard drive before the upgrade, so that if anything breaks, I can go off the network and reimage? I have an external HD with enough space to store a copy of my entire C drive.
