Ok, I only have hda1 and hda2

I changed bot permissions to RW. I set the password for root via the command line terminal. I "sudo su -" get the root prompt and run this command "mount /mnt/hda1 -o remount,rw" I also tried the same command with hda2.

I get this error:

mount: /mnt/hda1 not mounted already, or bad option

Why is it not mounting?
