If I could just add a touch more info here, for future reference for the OP:
It is *generally* not recommended to move a partition; particularly the START of a partition. Stretching bigger (to the right) never seems to be an issue, but trouble *can* occur when totally moving a partition.
I suggest instead, when possible, you MAKE a fresh new partition in the area where you otherwise would have MOVED one to, and then COPY the stuff from the old partition TO the new one.
This way, you can be assured you won't bork anything during the move, AND if something IS wrong with the new partition, at least you still have the old one as backup.
When all is proven to be OK, you can delete the old partition.
