I'm not sure which OS you are using, but try creating a bootdisk and going into DOS (or clever emulation of such) or boot from your win9x CD, and start computer with or without CD support. when you get to the prompt type scandisk. I am not on a win machine right now, and I dont remember the parameters, but type scandisk /? and play with the parameters a bit. you should be able to get the dos version running.
