  SVN rev 215511 on 2010-11-19 09:25:12Z by mav
  
  MFC r209683 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.
