LS-120 not recognize

[jeco]

I have the knoppix 4.0 on DVD and my computer is amd 1ghz with 512 mo ram, 2 hd, 1 cdrom, 1 dvd/cd writer, 1 floppy and 1 internal ls120. When I run knoppix 4.0 dvd live, when it has finished loaded and installed, in a console I mount my ls120 with the command:
mount -t vfat /dev/hdg /mnt/ls120
and I have no problem reading a floppy or a 120mg disk. But when I install on my hard drive knoppix 4.0 I'm not able to mount the ls120. Is there anything I have to download or does the command "mount -t vfat /dev/hdg /mnt/ls120" changed for something else. I looked in the dmesg message and my ls120 appears as hdg.
Thank you

What error messages are you getting?

Who are you trying to mount the drive as?

Does the mount point /ls120 exist?

In short, we need more detail.
