I have found TI 9.0 to really shine when it comes to backing up windows 98,98se and me to external usb hard drives. It works both in the old usb 1.1 and the new usb 2.0. I put a pci card in a older computer to change it from usb 1.1 to usb 2.0. I can backup this older computer with me in only 20 minutes. I can recover this computer in 20 minutes. This is the only software that I am aware of that can back up these older os's.
