Essentially scandisk won't run preboot. if I run it after windows boots I get scandisk has had to restart 10 times do you wish to continue warning. It's been too many yrs since I used 98 or me and I never used 98se which is installed. I know norton system works used to have a scandisk replacement but was wondering if there's any freeware program or dos tricks I can use to get this cleared up?
