Have you tried using the USB Duplicator Image Creator and USB Duplicator Writer
Even if you are only trying to make one Duplicate, instead of many,
these tools are designed to make exact copies.
PS; If you are duplicating the contents of a smaller drive/card onto a larger one
you will need to extend the partition, to get full use of the larger card. That is
easily done with a partition manager like the "MiniTool Partition Wizard" the
home edition is free.
