NOT replicated on Feather M0 Adalogger! The above code works without error (Class 10 Sandisk card).

[tannewt]

This error can occur if the card isn't formatted. fabitencourt, does it work when connecting to a computer or in Arduino?

[fabitencourt]

The black Verbatim 16 G one wasn't formatted. I've formatted fat32 with gparted and still the same errors on the same places. After many trials finally the black lexar 16G worked one shot. I'm happy...

Just saw the blue 16G on gparted and it had a 4 M not allowed. I've formatted on fat 32. I'll try with that too. No way. The only one is that Verbatin 16G black card you see on the photo. Lexar doesn't seems to work at all. Even if they work on arduino sketches.

[fabitencourt]

No way. Neither of Lexar cards are working. The black 4G and the blue 16 G too. Both Lexar cards don't seems to work for now.

[tannewt]

Did you get it working with a different card? I ended up with a Kodak card instead of Lexar but I'll give it a try today.

[tannewt]

I believe I'm seeing the same thing with a Samsung EVO Select card. It works with my Mac via card reader but produces an OSError 19 in CircuitPython. Looking at it now.

[fabitencourt]

I've downloaded the new version, candidate 2. I'll try it as soon as I can. I've noticed the DS3231 library is already there. Perfect. I'll give a try.
