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.
