Sorry, I guess I was unclear
ALL compression programs have a test parameter,,,,,zip -T some.zip
Because a flipped bit makes the zip useless
(or gzip -t some.gz)
OR,, you could try balenera etcher OR another image OR dd
(rather than gnome disks,, actually sounds more like an error with gnome disks)

Thinking a little more, probably etcher wouldn't work since I think it only does whole disk writes, not partition writes
