Getting started with MM - ?

Thanks - I’ll keep that module in mind and be sure to load it.

I wonder if the card failure is the result of a disk write operation being in effect at the time of power-off and the level of corruption actually ends up causing the card to be converted into a permanent read-only device (with the corruption). I have seen a SSD drive fail like this, although I don’t believe that it had anything to do with powering off.

At any rate - I’m usually good about having things like this plugged into a UPS and shutting them down properly.

@ember1205 I read somewhere that there is a utility to access the MicroSD card at a low level and potentially resurrect it. I did not dive to deeply into that as I have not had one fail and they are relatively inexpensive to replace.

I had a USB stick that was recognized at a severely diminished capacity than its actual listed capacity so thats what had me put my toe in to see if I could low level format it to the proper capacity.
