disk_io='none' should be used only if you do not need any data<br>
from the calculation, apart what is printed on output. 'nscf'<br>
and 'bands' calculations need as a strict minimum:<br>
- the self-consistent charge density,<br>
- the atomic positions (for consistency: the same for which<br>
the scf charge density was computed)<br>
- the Fermi energy (to compute occupancies)<br>
