Hi Alex, Of course, I was convinced to be in the CUSTOM mode ... 😫 Thanks a lot for the resolution from my lack of attention ! Alexandre

Ok, thank you for your answer :)

Thank you for your answer The Team. And do you know if the socket that I shown before is ok ? Kind regards

Great. Thank you Alex :)

Thank you for the answer. We used a sample rate of 48 kHz. Ok for the information about SanDisk Extreme. I haven't the details but the SD card is more or less detectable according to the tools used. We tested in the Mac Disk Utility but it doesn't work... Alexandre

Hi Sirius, Unfortunatly, I'm facing to the same problem with 2 SanDisk Ultra 128 Go. The configuration is slightly different but no majors. I used Hydromoth with firmware 1.8.1 with 3 lithium AA Energizer. According to the voltage, I'm sure that one batteries was empty ( 0.35 V ) but one was to 1.41 V. Today, the 2 SD cards are undetectables on my Windows computer. We checked on Linux and by a way, we could see there's a problem on the card.
