I formatted the card in Terminal on Mac to FAT32
My Mac Disc utilities recognizes the card.
BalenaEtcher will not find the card.
I had this issue the last time I tried to flash this card…and my card reader was plugged in on a USB extension line. Once I plugged the card reader directly into the iMac Body, it was recognized.
This time that does not help.
I have tried restarting, etc…etc…etc…to no avail. Anyone have a suggestion???
Do you have any other devices to try out this SD card on? Maybe another Mac or Windows machine?
Oh…thanks for getting on to help.
I did some reading and then disconnected all of my external hard drives (pain in the a$$ 
)…and then BE recognized my card. It’s all good!
