i only put the two fat32 partitions there as a suggestion, you may want one, you may want eight, depends if you like large files or not.
It helps to have small partition sizes if you are going to be using windows, since WHEN it crashes and needs to run scandisk, it will only scan the partitions you were actually accessing at the time of the crash. If this is just drive C and D, it might be 8Gb, say, saving you the time of waiting through another 32Gb of scandiak time.
