Does the dynamic disk show as one drive letter or two?
I agree that a utility from the manufacturer can do what computergroove describes. You need to get the correct utility though. Most makers will allow you to use their utility as long as one of the drives is their brand. Either the source or target. As I stated you can clone partitions without removing the drives. You boot to the utility and it can clone that way.
Using multiple partitions is actually preferable IMO. I recommend at least three partitions.
One for the OS and a few key programs. Second for the bulk of your programs and the third for your personal files.
One thing you need to be concerned about is 48 bit LBA compliance. That refers to the ability of the BIOS to work with hard drives larger than 127GB. If you BIOS can't do that then don't use the drive while directly connected to the motherboard.
In that case you would need to get an add in controller card.
If you already have the 200GB drive connect it up and boot. Watch the POST screens at startup to verify the drive is identified by both the model and FULL capacity.
