The idea was to replace the 3TB disk by 4TB disk on my Qnap Nas.
So I MOVED all my cr2 files to my other NAS (a Thecus with 4x 3 TB in RAID 5 )
Then I remove the 3TB disk from my QNAP and put 4TB in it
Then I move back my pictures from the Thecus to the QNAP
And now a hole folder (mariages pictueres) is missing.
I hope i just delete a filder from the QNAP 3TB disk , witch are untouched in a box... I hope to recover data from those disk
My actual pc does not support 3TB disk
