  SVN rev 209683 on 2010-07-04 07:42:52Z by imp
  
  Add a safety-belt.  If the identified disk has 0 blocks, don't attach
  it.  This can happen in some cases when plugging in SD/SmartCard PC
  Cards with empty slots.  It is better to detect this bogosity, and
  refuse to attach rather than panic with a division by zero (in one of
  many places) down stream.
