Could you explain this part?  E.g., did you run ‘wipefs -a’ to 
erase the old file system metadata?  Partition tables do not 
specify file system information.

Guix can take responsibility only for its own drive partitioning 
code (which, by most accounts I've heard, could certainly be 
improved); otherwise it's the user's and/or tools' responsibility 
to correctly wipe the underlying data.

Kind regards,
