terminal flashing causing sd card to be unreadable
I am currently trying to flash my SD card, but keeps getting this error that the sd cards unreadable, I tried using etcher and dd, and it keeps doing it?
I am trying to flash https://www.home-assistant.io/hassio/installation/
to an SD card so I can use it on my RPI, but why can't i open the sd card after a normal flash?
I am able to reformat, and then add files to it, but its only when I flash it breaks?
the SD card works fine, I can without any problem open it using my linux machine or Windows machine, so it is only this macbook - the one i prefer to work with, that seem to be buggy here.
Why? Format issue?
Flashing:

Can you post the actual error? Does the error occur during image writing or during boot attempts of the written SD card?

It happens after the flash has completed, and every time I re insert it

ddwrites without checking, or even caring, about what type of data, partition, or any filesystem it is reading and writing. It's possible that the Mac you are using can't read the partition information thatddwrote to the card. So, what happens when you try to boot the card in your RPI? .... The image file seems to contain a GPT partition table with a Microsoft Reserved partition as the first partition. I don't have a Mac handy to check readable of the written partition information.

When you write a rPi image to the SD card then you're writing a Linux filesystem (probably ext4) to it. MacOS doesn't understand this filesystem and so is reporting the error. Doesdiskutil listshow the drive and possibly partitions? If so then theddprobably worked.

@StephenHarris What you say sounds plausible except that the card works on Windows, and as far as I know there isn't ext4 support on Windows.
