Anyone who has ever had to reformat a computer (me

) or had to replace a hard drive (me

) will tell you what an absolute pita it is and that one of the worst parts is finding the drivers needed to get everything running back to normal. I have the Dell driver back up utility, but it has it's limits, only works if you can get online. I've had to look for drivers it didn't support, download a dozen wrong ones before I finally got restored.
Driver Magician is a free driver back up utility that will find and back up all your drivers to wherever you want them. This and a cheap memory stick can be a lifesaver!
