No, I have the disks in my pc.
The server can't boot the disks because Intel Storage says the raid has
a failure, because one of the disks has no raid information. But as I
read them both yesterday they had, now (see the last attachment) one of
them has none.
It makes no sense... I need the files

Intel means "yeah make a new raid, with data loss" that's no option.
