Thank you for your reply.
Connected to another Mac, no data is displayed on my drive. Yes, my disk mounted on my Macs except that its name has changed.
It also requires you to know that I am French and my English language is poor. This is the second time I plant my drives; the last time there were only 2 and had taken a month to recover some data and sort them. This time they are 3 drives which are down.
thank you again
