Test Etcher, a multiplatform USB stick burner
Could this replace dd graphically and on multiple platforms?
First we should test whether it works in the first place, then whether it modifies the ISO image in any way.
- Download and verify an ISO image
- Burn it on a USB stick using Etcher in Windows and Mac
- Report a few screenshot of the process to get an idea
- Start from this USB stick
- Try to understand if Etcher does a byte-to-byte copy (like
dd) or something more fancy
- If it's like
dd, try to compare the checksum of the ISO and the resulting USB stick
- If it's like something else, investigate what it does, compare the boot option, the boot loader, etc.

I tested version v1.0.0-beta.3.
- Windows (7 x64):
1.You have to install the software
2.When you launch the program it ask you for admin rights
3. You select the image iso and it select automaticaly the USB key if there is only one
4. You click on flash
5. Burning starts
6. It looks like it's verifying the integrity of the image.
Process is fast, it tooks me around 04:30 min with an USB 2.0 key.
- Debian (Sid, x64):
1.You don't have to install it, just untar the archive and launch the bin.
2. If you don't run it with priviledged rights, it will show you an error and you will have to run it with sudo ./etcher, it is not user friendly but it should be fixed soon: https://github.com/resin-io/etcher/issues/277
3. Same process than Windows, select the file, they key (if there is more than one), click flash and wait.
It is faster on Debian, it tooks around 03:00 with the same usb key.
The checksum is not the same than a device flashed with dd. I think it it due to the strange things it does to the partition table.
There is not fancy bootloader, the Tails booted seems legit.

hi, i've attached screenshots of the 6 steps of going through the process of wrting tails to an usb stick on osx.
on osx, too, you're asked for admin permissions, it was pretty fast (~ 2 minutes). in osx too, the partition has another hash than the image.
the tweets elouann posted make me a bit skeptical. as far as i can see, etcher is a frontend for etcher-cli, which has the function to write to disk in:
https://github.com/resin-io/etcher-cli/blob/master/lib/writer.js, which again uses the resin-image-writer module, which has the write function on https://github.com/resin-io-modules/resin-image-write/blob/master/lib/write.coffee

Thanks for the screenshots, that's really useful! I like the interface because it's simple.
Still, I wonder why the result has a different hash than the ISO. It would be good to investigate where the difference comes from.
Elouann's tweets mention 130MB of download. I see ~50MB on the Etcher website which is still quite a lot for a simple app like this (UUI is 1.1MB). I tried to open the tar.gz but the content is too weird for me to understand. There are two big binaries: app.asar (34.0MiB) and etcher (21.4MiB).
Also, both projects are almost one-man shows and less than one year old:
So, my final take on this is that it's a cool initiative, it's super cool that it's multiplatform right from the start and it could replace UUI for Windows and dd for Mac but the project it too new and green for us to consider this as a replacement right now.
Thanks to everybody who did the tests for me!
