Yes the GPT overwrite the superblock.  The GPT uses the first 17KB of
the disk, and the superblock was at 4KB from the start.

At least given the data should start at 1MB from the start, it should
not have been overwritten.

I do always like disk images before I try anything like that.  I am never
quite sure what create will do although it will likely do the right
thing at least if you get the order right.
