How huge hard drive do you mean for *windows 98SE*? The maximum capacity for windows 98SE is 120GB. No more than that and this is the *actual* hard drive size. You can safely run windows 98SE on hard drive 120GB or less, like 100GB, 80GB. Not partition size. Win 98SE corrupts data if hard drive *is larger* than 120GB capacity.
Drivespace was used on "too small" hard drive that person purchased a computer back then around 91 or 92 or so, with 40MB or 60MB few years ago, now trying to run late DOS stuff now needs the drivespace on. Now there is *NO need* for that enabled anymore now due to plenty of hard drives out theren now. When you are playing with large hard drives, it is no issues using 2GB partitions using DOS. Second, if you need to access it other ways and something breaks down, you have no longer have accessible to the partitions that had drivespace enabled. I prefer off.
When I hear DOS, I assume DOS 6.22, 5.x. Windows 98SE comes with their own DOS that was partial booted during the windows 98SE startup. But DOS games and DOS programs were not designed to handle so much and best placed there on up to 2GB partitions.
I like less complications.
