is not a cloning program. It will create, resize, and merge existing partitions a well as perform a few more neat tricks. The version you have will determine with which file systems it is compatible. In order to transfer data, you need a program that will do so. Some will, within certain limitations, expand the partition size for you. If you have XP Pro on the existing drive, it will need to be SP2 in order to utilize the full 200 gigs of your disk. A relative of Partition Magic is Drive Copy. It should be able to do as you wish. You can always just reinstall XP on the larger drive (again, you will need SP2 to use the full size of the drive) and copy the data over later. No 3rd party utilities will be required. It will require reactivation but you might face this with the transfer process anyway.
