The checksums included in PG are page-level and therefore there simply isn't one to look at if the file is zero bytes.
And even if the file wasn't zero bytes you can't tell from the per page CRCs if you have all the pages you should have. You could have extra pages that aren't supposed to be there or missing some (or any mix of the two). A per page CRC is useless for those cases.
