Thank you very much for all information
. I just realize that my memory was dead this day and I solved to fix the reader with your post
.
I only struggle about the size of the data partition that can be extended. After some tries reading @Better_Boy instruction without succes I used fdisk sectore recommandation deleting and creating the partitoon and now I hace "something working", but in this case the reader sees the memomy at a total of 4Gi and a free space of the real partition size. Have you the same behavior ? I didn't succeed to keep book reading history but no matter I prefer to have a working reader than a read only xD !
