I don't know if this is in the right place but...
I'm trying to write this image of Raspbian Stretch--which I believe should be the most recent--to a micro SD to run it on a Pi 3:
https://www.raspberrypi.org/downloads/raspbian/
This is the micro SD I'm using:
I don't have an SD reader on my PC, so I'm using the USB adapter pictured. Etcher will write the image but fails validation. I thought maybe it still wrote alright anyway so I popped it into the Pi and I got this error:
Could not expand filesystem
There is also mention of a few missing files. I did some digging and most sources agree that it looks like a faulty write. The typical solution is to use Etcher (ha) so I'm guessing the problem is that somehow Etcher doesn't like the adapter.
Does anyone have any ideas?
On an issue at etcher github repository, they say it could be because writing an image using laptop on battery than it cannot provide enough write speed as needed to write the image. – Tiago Gouvêa – 2019-01-24T22:53:40.097
