In that case I don't know why it didn't finish writing then, unless my temporary connections between RasPi and flash moved a little bit or just aren't tight enough for a good signal. Cable length maybe - signal path is RasPi -> 40pin IDE cable -> hookup wires (15cm) soldered to the pads on the chip. Now that I've got more female-female jumper wires I can go direct to the Pi to shorten the distance drastically. Currently I've got the flash hooked up to a parallel port on an old desktop so I can use SPIPGMW which has just dumped the whole 16mb to disk so I can try writing it back to see if it fails indicating a bad area in flash.
