Cyton Daisy SD card empty file + multiple files after session Issue

Hello,

We've encountered challenges with the Cyton Daisy SD card files. In two separate experiments utilizing pairs of Cyton Daisy devices, data is recorded onto SD cards. One problem we've noticed is that some session files end up empty. Additionally, there are instances where a single session generates multiple files: one large file and several smaller ones containing just a few lines of data. Our devices are approximately 1.5 to 2 years old. We're seeking solutions to address these issues.

Thank You

    Shyamal, hi.

    Please email customer service: (contact at openbci.com). Are the failures happening on both units? If so then it seems less likely this is a hardware failure. Are you using the recommended cards?

    The smaller cards work better. I do see your previous thread. That was not emailed to customer service?

    Yes, I noticed it on both devices.
    Yes, we use recommended cards (SanDisk 16 GB/8GB).
    No, we haven't contacted customer service yet. Previously, we used a USB extension cord for tapping the dongle on participants' shoulders to make this issue less frequent. However, it is now critical for us to not have this issue occur frequently.
