I'm Lost.. need some help please...

Ok i figured out the serial code so i'm now using JJ OS 5.39

here's what i dont get...

when I hit mode and then pad 2 (load) it takes me to the "load page."
to the right of where it says "load" it looks like this...

Load: MEMORY CARD.

I turn the data wheel to the right and it says
wait...... and then it looks like this..

Load: HARD DISK

I turn the data wheel to the right again and it says
wait...... and then it says

Load: CD (NO disc)

if I turn the data wheel to the right one more time it says
wait...... and then it looks like this

Load: INTERNAL

My question is... what is INTERNAL. I see all these sounds/programs but what exactly is internal?? how can I get to these sounds. cause i'm a bit confused. Is this my internal memory. if so how can I delete these sounds. or add to them.

If I go to the "save page" and try to save something to "internal" it says...

mpc [ INTERNAL ]

and it doesn't allow me to save,, if i highlight "internal" and hit the "window" button it takes me to a "property" page that looks like this...

Device :
Free: 0.0 MB

can someone PLEASE help me out here!!!!!

i think this is my internal memory. If it is I would like to add some sounds to it so when I turn on my mpc it automatically loads the sounds i want. and not the "stock" sounds. also it says I have 0.0MB free so how do I make some space.... PLEASE HELP ME OUT!!! thanks guys.

It is in fact your internal memory.
I would suggest leaving it alone and just buy a Harddisk or a Memory card.
You can turn off autoload in the load screen so those factory samples and programs don't load when you fire up the mpc.
If you want a bunch of samples and programs loaded automatically you can make and autoload folder on your memory card/harddisk and it will load everytime you turn on your machine.
You'll have to set autoload to the storage device (harddisk or memory card) you put the autoload folder on for it to work
