Hmm... looking in the datasheet I have, it says: Flexible Erase Options – Page Erase (512 Bytes) – Block Erase (4 Kbytes) – Sector Erase (64 Kbytes) – Chip Erase (32 Mbits)
The dataflash is normally 528/1056 bytes per page. D versions can be configured to have a 512/1024 bytes per page but that is wasting a couple of percent of the dataflash.

which would indicate a third combo, different from mine and yours :) --- 16 blocks/sector and 64 sectors... The code only does page based so far, so I didn't catch this.
