Indeed -- rule it does.

dd (from whence ddrescue sprang) has been one of my best friends for
at least two decades.  I recommend that *everyone* practice its use
for those times you *really* need it.  Try:
  - cloning a disk
  - cloning a partition
  - pulling out the MBR from a disk

All this and more awaits those that take the time to learn the powerful
tools that are available from un*x-like OSes...
