I used etcher to flash the latest Hass.io image file to my 32 Gb card. The flash created two partitions, a small boot partition and an unformatted 30 Gb partition. Neither is readable by windows. Is this correct? Should I format the second partition before I use it on my Raspberry?
I know once the Hassio image is on the card there are partitions that Windows cannot read. It is possible the image you installed unpacks itself onto the other partition in addition to downloading parts from the Internet.
I have run the Hassio HassOs image on a 32 go card. I am currently running Hassio on Raspbian Lite.
Again I followed the directions on the Hassio site. I flashed Raspberry Pi 3 Model B and B+ 32bit. What was created was two partitions. One small one that is the boot partition and a second one that is unformatted. The is no documents that say what to do next. What I see are documents on the need to create config files and a directory on either the boot partition or on how to do this with a usb drive. To me something is wrong either with the image, or the documentation. I don’t think it is an Etcher issue as I tried other programs that can write from the image file and the same two partitions were created.
Have you tried to boot the RPi with the card?
