Quoting from the document referenced below:

  We have tried these commands but they have not quite worked for us
  mount -f -t -s c:\\cygwin\\lib /usr/lib
  mount -f -t -s c:\\cygwin\\bin /usr/bin
  mount -f -t -s c:\\cygwin /
  mount -f -t c: /cygdrive/c

The reason the commands didn't work was because the last command is just
plain wrong.  The correct command (for their purposes) would have been

  mount -c -t -s /cygdrive

after which there is no need to re-mount each drive separately (or
reinstall Cygwin).  Plus, there's a typo on that page (although in the
text that would be made redundant by the correct command above).  I didn't
find any information on the page on how to notify the maintainers of these
errors, but if anyone wants to dig deeper, it would be nice.

The above is one of the main reasons why we frown upon external
documentation.
