Hi there,
I confirm that Etcher from v1.5.107 should be able to do what you just described. The only problem is that in the recent past we had some clone issues that occurred on Windows and only on certain Etcher versions. I would suggest you to read this forum thread before doing any kind of try Balena Etcher - clone drive, now have two blank drives - #28 by zvin, since this could cause a complete erase of all data.
