Multiple partitions for my SD Disk II emulator

[xboxown]

   Hey,

I own an SD Disk II emulator and it have an SD that is 8 GB in size but have one single partition of 32 MB on it. I want to make multiple partitions of proDOS of 32 MB but when I go to advance disk utilities to partition it, the partition button is disabled.  How do I make it in such away that I can be able to partition the SD drive?

Thanks in advance.
