NTFS question

Okay, I have a question regarding the NTFS file system.  I just got my hands on Windows XP RC1 and so I'd like to see what the hoopla is that M$ is clamoring about.  I would like to use NTFS as the file system when I format the drive.  However, I'd like to return it to FAT32 once I'm done reviewing RC1.  So, my question is if it is just as easy as running fdisk on the drive and deleting the primary partition (NTFS) and reformatting the new partition using FAT32?  Or am I going to run into a ton of trouble from trying to convert the drive back to FAT32 from NTFS?
