If you can't for some reasons succeed 
we @ https://www.RecuperoDatiRAIDFAsTec.it 
can recover it with very low flat rates

BEWARE if one drive went failed and ALL the drives have the same age
nothing can guarantee that none of the other drives is worn too

the HINT is to clone all the drives as we do on regular base 

then work with the clones

if you wanna exchange info's, the +39348******* number on the website has WhatsApp

Kind regards
