Where I read Akoya something rings for me.
Please check again exactly how many partitions you have with the Partition Wizard or Disk Management. Aren't there 2 smaller partitions hiding somewhere? I also have an Akoya on my wife's computer. The guys have created 4 primary partitions, creating another partition is not possible. The only thing that helps is formatting the whole disk (i.e. deleting all partitions) and when creating a new one, make sure that you create a primary partition (which must then also be active) and an extended partition. Any number of logical partitions can then be created in this extended partition. The whole thing only works under Windows, for that I have Partition Magic from Symantec on CD. With the WinXP CD you can also delete and create partitions, but I don't know if the Win7 CD works.
