Follow-up Comment #6, bug #30061 (project avrdude): Upon re-reading, I see the "with auto-erase off" being mentioned. In that case, it's simply a usage error. Trying to write data onto a device that is not guaranteed to be erased is asking for trouble. If it were not operating using a bootloader, but plain ISP mode, the result would be for *any* of the actual written pages to become the logical AND between the previous and the current data values.
