It would be helpful if you entered the commands properly. When asked for the results of mount, that is the command. Not mount /dev/<something>, just the single word mount, as root. The same for the df command. Actually the command we want is df -h, but that is by default aliased to df. In my case I have other aliases, so the defaults are no longer in effect on my machine, so I use the full command, The results should look something like this.
[root@littleboy ~]# df -h

/dev/sdc14 30G 9.3G 20G 33% /mnt/here
Each mounted partition is listed, with its total size, the amount currently used, as well as the directory on which it's mounted.
[root@littleboy ~]# mount
/dev/sdc15 on / type ext4 (rw,noatime)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,mode=0620)
/dev/sdc5 on /home/polack/Documents type ext3 (rw,noatime)
/dev/sdd5 on /home/polack/Documents2 type ext3 (rw,noatime)
/dev/sdb6 on /share7 type ext3 (rw,nosuid,nodev,noatime)
/dev/sdd6 on /share9 type ext3 (rw,nosuid,nodev,noatime)
/dev/sdd9 on /movies type ext3 (rw,nosuid,nodev,noatime)
/dev/sdc12 on /movies2 type ext3 (rw,nosuid,nodev,noatime)
/dev/sda5 on /tv type ext3 (rw,nosuid,nodev,noatime)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sdc14 on /mnt/here type ext4 (rw)
Here again the partitions and their mount point are shown, but rather than the amount used, the filesystem type, and the mount options used are shown.

This shows all the partitions on all the hard drives present on the machine. The results of these commands from your machine will give us the information we need to be able to help you. Depending on what we see, we may want results from other commands as well.
