I am building a new rig. My last build (current machine) was 5-6 years ago. I am still running Windows 98SE. One of the biggest problems I have had with this machine is the need to reformat and reinstall 98SE every twelve to eighteen months. I know that 98SE has a reputation for degrading over time. In additional this has been exacerbated by my habit of installing and uninstalling lots of apps, primarily games. It seems that each uninstall results in some ghosts of the program being left behind and other needed files, often shared ones, being deleted. However it often seemed that I was required to install my apps and games to the OS boot drive in order to get them to work properly. I hope to avoid this situation with my new machine. I am wondering under XP how many of these programs can be installed to (and then deleted from) a drive other than the boot drive and if doing so will result in a cleaner install of the OS. I have noticed what appears to be a trend in people building machines with multiple drives. Is this due to people trying to accomplish the same thing as I am or is it for another reason.? I mean what are people doing with a second drive in the 200 to 300 Gig range if they aren't installing apps there?
