Welcome to fdisk (util-linux 2.34). Changes will remain in memory only, until you decide to write them. Be careful before using the write command.
GPT PMBR size mismatch (209715199 != 629145599) will be corrected by write. The backup GPT table is not on the end of the device. This problem will be corrected by write.
