Welcome to Vodafone Community
An SD card in your Mac can't be formated or repaired? Well then this isn't a vodafone problem. The SD card is failing due to a hardware fault, and it's lucky you got it backed up in time.
I just replaced had a failed micro SD card. It was 4 years old, and I was able to back up the data before it completely failed, like you.
Thanks for keeping us updated with this.
It does appear that the issues you're experiencing means that your SD card is corrupted.
I'd advise testing a new SD card in your phone. To transfer your data over to your new SD card, you can use the back up you've created on your computer.
