The "--list" command to 'dd' gives a whole bunch of stuff:

some of which appear to be entire disks, not partitions.
Since I was trying to write into a specific area of an SD card connected via a
USB adapator, I took the path which seemed to be that of least resistance,
which was to use a partition which covered the blocks I wanted to write.
If I needed to write the boot block (which contains the partition table), I'd
have probably tried using some of the other devices in the list, but since I
didn't need to, I decided not to get diverted from my real goal by trying
other devices.
Maybe it won't work for what he needs to do. But it worked fine for me, doing
something very similar, so I thought I'd mention it.
