Flash will report a logical sector size of 512 bytes and fib about
physical sector size of 512 bytes also. Optical media has a sector
size of 2048 bytes, and the ISO image contains an ISO 9660 file system
so the terminology may just be getting confused between the actual
flash as a physical device and the fs that's on it.
