G'day, W Collins
Win 98's defrag is very slow. You can use the '98ME version which is much faster and is not as fussy about other running processes. However, screensavers that access the hard disc cause both defrags to re-start. After 10 restarts they both quit, so to be safe you usually need to de-activate your screensaver before defragging.
I can't remember where I got the 98ME defragger from, but I still have it. You could get it from a friend who uses 98ME or I will email it to you - it's quite small, about 76kB. PM me if you want that.
You might find
this interesting.
Cheers
