if dd is used to write block device, would destroy in-use devices, or LVM, partition tables on devices. Before opening the output, probe with libblkid and warn if content is recognized, prompting for confirmation.
Checking whether a device is mounted does seem potentially useful. Checking whether to overwrite existing file system structures seems less useful, as that would be a very common scenario. Also that functionality adds the libblkid dependency which isn't ideal. thanks, Padraig
