Disk Managemenet and Dynamic Disks

I have a pc that had Windows 98 installed on it. It now runs Win2k Advanced Server. When I installed Win98, I used all of the available disk space, formatted in Fat32, and therefore I do not have the necessary 1 mb of free space in order to convert the drive to a dynamic disk. I have converted the drive to NTFS but would like to take advantage of some of the features of using dynamic disks. Is there a way to free up the 1mb of space without losing any data on the disk? Any help would be appreciated.
