OK for this point. But the remaining problem is: why gparted does not
see the partitions?

fdisk and df can see roughly 2 partitions 20Go+480Go and gparted sees
that mostly this disk has non-allocated space while the linux partition
had 44Go of data on it...?


Moreover, I tried to extend the small ext4  partition (2.84Mio according
to gparted) to the next "non-allocated" space (465,45 Gio).

gparted warned me that all my data will be lost... OK, I launch the
dog.... It ran for 2 hours.... I stopped it and... nothing was done.
even my data were not lost!

Is gparted working?

Thanks for answering.
