the new disk is up and running after less than 4 hours later.
This disk is were Boinc save all past and present data (not the DB, that is in another more faster one) and the downside of a Boinc installation is that space in that area will grown day by day.
As the old one last for more than 3 years, we have at least other 3 years of data to process before fulling this one
