Hi Jerry, I run Win 98SE and use XXCOPY to clone my C:\ drive to my D:\ drive on a weekly basis.
It clones everything including the O/S, registry, programs and data files and can be used with all systems from 95 to XP.
XXCOPY can be downloaded FREE from click here and to use it, you go to Start, MS-DOS prompt and type :-
xxcopy C:\ D:\/CLONE
If things ever go wrong with your C:\ drive, simply clone it all back from the D;\ drive to the C:\ drive.
I hope this is of some use to you.
