I often use flash cards in my Linux laptop ( from a camera) and once
forgot to unmount the card before ejecting and swapping the card. Even
though the cards had been mounted read only, the card I inserted ended
up with a corrupt file system.
Ive had NO problems if I do the right thing, but corrupting the FS on
a read only mount certainly surprised me!.
