In general, that is what you would do with two disks of identical size.
If the disks are NOT of identical size, then you will probably need to
copy each partition: copying the whole disk will also copy the
partition table. And the partition table for a smaller disk will not
be suitable for a bigger disk....
I.e. first run "fdisk -l /dev/sdb" to list your existing partitions
and create similar partitions on the new disk. (You have to chance to
re-order them here if you want).
Then copy each partition separately:
dd if=/dev/sdb1 of=/dev/sdc1
etc. (copying multiple partitions in parallel will actually take
longer..)

That error message is new on me...
Hope this helps
