kano-burners suggests wrong disk to burn to

[hzulla]

Here's my output of parted --list

$ LANG=C sudo parted --list

If I start kano-burners, this debugging output will appear:

sudo LANG=C ./bin/kano-burner

kano-burners will then offer to burn onto 'ATA HGST HTS541010A9'.

I preferred not to try that. :-/

Ah, so the error is that src/linux/disk.py is using two different tools, parted and fdisk. But those may return the disks in different order.

I had the same thing, but didn't notice until I had closed the window and looked at the shell output.

After lots of futzing around trying to make it recognise the SDCard at all, I finally saw the 7.9GB size for the card listed as the only option and just selected that without properly checking the device label. I probably had a false sense of security having seen that kano-burner checks it won't write to a HD and it never listed the HD at all earlier. So much for that.

The output isn't entirely clear whether it or not it overwrote anything on /dev/sda. It doesn't sound like it did, but just to be sure I'm in the middle of taking a backup before I do anything else.
