I don't know ther real reason for the /s switch (transfer system files I know) but before you format C without the /s switch ,format a floppy with the /s switch. For thouse mome knowlegable correct me if I'm wrong , but I would use fdisk and remove partritions and then add them again.

Once you have the drive formatted then boot from your disk again and type sys C: . That will probably be easier than trying to figure out where you dos memory is going.
