First day: no partition to read ! (xfs_repair /dev/sdb2 -L
...only superblock search: found : nothing ! Above-change: sdc2 to sdb2 because of 3.Hdd-with-recovery-space-300GB )

2 days later ...after labor work:

solution:
"photorec" saved my data (recovered: *.odt *.ods *.ts *.pdf *.txt and for sure: all photos) !
"testdisk" saved my partition !

so aptosid saved my day Smile
