Description Shalok Shalom 2015-07-28 14:30:26 MSD
Please implement isomd5sum, in order to check the ISO automaticly before it get written on the stick. This improve the introduction by novices and make it in general more easy to get a proper installation and live media.

Is it possible to check the md5sum once the writing process is done?
That will verify the usb stick as well? 

(I mean, of course, instead before the writing process.)

To be 100% sure, you'll have to check twice: first the ISO file itself (to verify it was downloaded correctly), then the USB stick (to verify it was written correctly). If you check only the USB and get an inconsistence, you'll have no idea whether it was a write problem, or you had a broken ISO in the first place. But still, I imagine how long all this would take...

Hi Konstantin, thanks for your quick and nice response.

I think, an additional button, named something like "Check and Write" who check twice and offer a corresponding message (All is fine / Your USB Stick seems to be broken / Your ISO seems to be broken, please download it again: [Download URL/Torrent]) is an great idea.

People, who know, that there ISO and Hardware work fine, are still able to launch the writting process with the current button, while casual users get a comfort offered, which is afaik unique. :D

I think also about a forked torrent client like qbittorrent, which get bundled with the Image Writer and the torrent file: Resulting in an very simple installer. :)

This torrent client can check the md5sum, the functionality is already implemented there.

So far as i as an casual user understand that, is it very simple to create something like that ?

The client download and check the ISO, if all goes fine, open the Image Writer automaticly, preloaded with the ISO all get vertifyed then again ?

I want to mention, that we talk here about the preparation for an OS installation - so i think, that 1-2 Minutes more to wait are fine, in order to get a proper media, in each case. 

We all know, that issues, which are the result of an broken ISO is unlikely to detect by a newcomer and look like distro specific errors to them. 

A correct written media is of course very important and the current process in the FOSS world seems to be easy to simplify. :)
