i do the same thing as bob for updating eeprom / 'flash'. that lets you know if a whole write
sequence completed ok.

the other thing i do is check each byte after i have written it - i can then detect any errors and
decide what to do about them... in my system i only update the data infrequently, by user
intervention, so i can just tell the user that the write to address NNNN failed. the user can then
try again or put the system in the bin or whatever...
