Data Recovery using R Studio for Mac - LaCie 2BigQuadra

[french]

Hello guys, just to let u know that i finally found a french company (i can provide the name if anybody wants) who did it of course for some money but something i found quite fair.
It took some times but they did recover all the files, almost 4To.
They told me it was only a box failure (my dd's were fine) so the job was to find the raid 0 parameters. Of course they did not tell me exactly the tricks but those Lacie 2big do have an offset between both drives if it can help anybody in the future.
Thanks to those who helped me here
