Emax

Hey, my dad just gave me an Emax 11 keyboard a couple
days ago and I've come to the part in the manual about
sampling. It said for me to erase the bank memory for
some reason, but I didn't want to do that and risk
losing any presets. So I just bought about 40 3.5 pc
formatted floppy disks. When I put one in and tried to
do the function of Sample or any function for that
matter, I got a loud clunking noise and something that
read disk error. In fact even when I tried to do the
Master function and went to format, it did the same
thing. What am I doing wrong? Thanks for your help.
