So can you run scandisk or not? I would try running scandisk first (in windows, and then if you can't, in dos as suggested above). If it runs successfully, check the results - do you have lots of bad clusters? bad sectors? Because you could have a bad drive...<br><br>also, what sort of pc is this? how much memory, hard drive space, etc. Because win98 doesn't run too well as it is on "older" (in pc years) machines. Also, Microsoft's disk defrag is pretty slow, though it's improved some from win95 to win98.
