I suggest France´s BEA to learn
ASAP how to differentiate between a CSMU of a FDR to the one they found, from the CVR:
BEA 1st May 2011 briefing
The investigation team localized and identified the memory unit from the Flight Data Recorder (FDR) at 10 h UTC this morning. It was raised and lifted on board the ship Ile de Sein by the Remora 6000 ROV at 16h40 UTC.
The photos published by BEA are from CVR CSMU:
