Good idea. Thanks.

A-ha, it turns out I can't:

  $ sudo dd if=/dev/mmcblk0
       1  abcdefghijklmnopqrstuvwxyz
       2  abcdefghijklmnopqrstuvwxyz
       3  abcdefghijklmnopqrstuvwxyz
       4  abcdefghijklmnopqrstuvwxyz
       5  abcdefghijklmnopqrstuvwxyz
       6  abcdefghijklmnopqrstuvwxyz
       7  abcdefghijklmnopqrstuvwxyz
       8  abcdefghijklmnopqrstuvwxyz
       9  abcdefghijklmnopqrstuvwxyz
      10  abcdefghijklmnopqrstuvwxyz
      11  abcdefghijklmnopqrstuvwxyz
      12  abcdefghijklmnopqrstuvwxyz
      13  abcdefghijklmnopqrstuvwxyz
      14  abcdefghijklmnopqrstuvwxyz
      15  abcdefghijklmnopqrstuvwxyz
    dd: reading `/dev/mmcblk0': Input/output error

Banjaxed card it is, then.

Cheers
