Akai S1000 / S1100 samplers

Hello, here goes my first question,

It seems that I am not getting the full capacity out of my zip disks.
When I go to format a disk, the partition size option only goes to 60M.
I remember reading somewhere that the S1000 will make more than one of
these, and then size the last one to go to the end of a disk, but I
can't seem to access these other partitions. Am I doing something wrong?
