After that, the copy worked as per original.
But wouldn't the DD command overwrite everything on the SD card including the partitions?
Strangely, it didn't.
I also tried reformatting it, and it ignored the partition. I think it's because the partition has a different drive address.
Surely whether dd overwrites the partition table or simply the data in the partition depends on which device file you specify to dd. Generally the device file without a number suffix is the whole device and the one with a number suffix (which is usually the one that is mounted) is a partition.
Also the card must not be mounted, particular if it is the destintation, otherwise filesystem activity may then overwrite the data from dd.
