You should be able to write new firmware, sure - my colleagues
did add support for flashing sd(7d) to fwflash. I would be very,
very wary of doing so, however, unless you have documentation
from your disk manufacturer which (1) gives you the structure and
instructions definitions, and (2) lets you verify that you have
a valid image.

Reading firmware from the disk is not supported with fwflash.
