I installed WINDOWS XP and could no longer use my SuperDisk LS120. I also had accidently tried to format my MAXELL 120 disk and made it unusable. After down loading the above file I was able to reformat my MAXELL 120MB floppy with my LS120 drive and was able to once again read my old drives. I fouind it to be an excellent program and had no trouble using it. I would advise reading the text file that will be un zipped with the program.
