Disklavier

I have a Disklavier III, and I am trying to download recorded performances 
from the Yamaha Piano Soft site and the Piano-e-competition site.   I am using 
2-HD 3 1/2 inch disks.   My disks are formatted for IBM systems. I have 
downloaded the Yamaha downloading software for the Yamaha Piano Soft recordings.   Am 
  I doing everything right so far?

Of a half dozen disks I downloaded from the Piano-e-competition, only one of 
them worked when I put it is the Disklavier drive.   I now realize that I 
probably needed to un-Zip the files first, but when I do un-Zip them, I get a 
message that the disk does not have enough room.    Do I need to save the unzipped 
files to the PC and then copy them one-by-one to individual disks? The 
formatting on the Yamaha downloads is not recognized by my PC.   What is going on?   


I am well prepared to acknowledge that I have missed a step or two.   The 
classical selections available commercially are sufficiently limited that I like 
this technique of downloading concert performances.   Hence, I want to get the 
process to work properly for me.

Is there a technical reason that I have to use the 3 1/2 inch disks instead 
of CD's?   The Disklavier drive on the Series III accepts CD's.   Is not the 
data entered on the two different types of disks the same?
