take care to protect shared structures in io thread
if flash corruption is detected try and recover whole files
overwrite format in erase to make sure erase happens
output useful messages at critical times
a block is 64k a sector is 4k, rename internal variables appropriately
cope with log wrapping when sending log listings over mavlink
