There is an opportunity to do the verification at a higher level. This
would standardize verification after right copying of the block/segment
in cp command. What do you think? That would leave the driver
simplified. I am personally not too happy to generate interactive
messages from within the driver. Different flash drivers emit different
messages. A unified user experience would be better in my opinion...
