Akai S1000 / S1100 samplers

Hi Group, I bought a cheap S-01 as an introduction to sampling, I have 
succesfully sampled my Minimoog which I no longer take on the road.

However I am interested in playing some profesionally made samples on 
the unit. I know the s01 can play s1000 files if the sample rate is the 
same on both units, so I bought 3 CD's containing various samples, 
however my PC won't recognise that there is anything on the disks, my 
idea being to tranfer the sounds I liked onto Floppy disk.

Can anyone inform me of how I can get samples into my s01 ?

All the best Neil.
