Allora se eseguo dal prompt il comando biber checco mi dice che non trova il file checco.bcf.
Ho quindi eseguito una volta il file checco.tex con pdflatex da TeXstudio e mi sono comparsi i vari file, tra cui checco.bcf.
A questo punto eseguito biber checco dal prompt ed esce questo:

Il file checco.blg che ho è questo:
