*** Root partition has already been mounted read-write. Cannot check!
For filesystem checking to work properly, your system must initially mount
the root partition as read only. Please modify your kernel with 'rdev' so that
it does this. If you're booting with LILO, type:
  rdev -R /vmlinuz 1
         (^^^^^^^^  ... or whatever your kernel name is.)

If you boot from a kernel on a floppy disk, put it in the drive and type:
  rdev -R /dev/fd0 1

This will fix the problem *AND* eliminate this annoying message. :^)
