Not the FDR but the memory module. First stated by President Hollande but also confirmed by other sources, the FDR was discovered the second day with the memory module dislodged (meaning gone). Observing pictures of the recovery, as expected when an aircraft hits a steep slope a lot of dirt was dislodged and mixed with aircraft debris rolling down the hillside. I have watched videos of recovery workers digging into the loose soil to recover components with part protruding from the soil, and with such a part in one video there was an electronic circuit board. FDR recovery still could be as easy as picking up the right piece of debris or it could mean sifting through tons of soil.
