WD My Book World: clean (empty) Time Machine storage on disk

I had problem with connection to WD MyBookWorld. I solved the problem by deleting via ssh folder /DataVolume/.timemachine and created the new one with 777 permission and reselected volume to backup in TimeMachine.

rm -rf /DataVolume/.timemachine
mkdir /DataVolume/.timemachine
chmod 777 /DataVolume/.timemachine

Script takes some time to complete, because time machine creates a lot of tiny files.
