" the hda1 and hda6 are located in /dev/i2o/ and I do not know why I can not mount them."
I think that you are trying to mount the wrong devices. Try:
mount -t vfat /dev/hda1 /lee
mount -t vfat /dev/hda6 /grant
You can look at /etc/fstab and find the default directories and file system types for /dev/hda1 and /dev/hda2.
