I just tried my new unit today. It seemed to be working fine but when
I uploaded the flight to the SD card it was "busy" for a long time

these new units??

My Colibri II took a few tries to recognize the factory MiroSD card.
Wouldn't turn on. Tried pulling the card out, still would not turn
on. Plugged it in for a while, still no. Let it sit for several
hours off the charger then it worked. I think flight recorders are
sensitive to change. Our club has an EWMicrorecorder that exhibits
this type of behavior. I think it requires the SD card be formatted
FAT, not FAT32. Since then I only use factory issued memory cards.

Try putting the card back in if that was the state it was last time it
was used. Let it sit a few hours and try.
