but fdisk -l w.qcow2 shows totaly wrong!
You can't use fdisk on a qcow2 file (as it is not just a true image of a raw disk). I highly recommend this guide [1] in order to understand the different file formats used for disk images.
Regarding your first question: yes. You can convert from a raw image to qcow2.
