Writing an iso to usb gives unexpected output

Hey experts
I have a verified QubesOS installation iso. All the digests were correct. I followed the docs on the official website. The command and the output after writing the iso to usb is the following:

sudo dd if=Qubes-R4.1.0-x86_64.iso of=/dev/sda status=progress bs=1048576 && sync
5945425920 bytes (5.9 GB, 5.5 GiB) copied, 330 s, 18.0 MB/s
5679+0 records in
5679+0 records out
5954863104 bytes (6.0 GB, 5.5 GiB) copied, 386.192 s, 15.4 MB/s

As you can see the bytes before and the bytes don’t match. Is this an issue I should be worried about? Or how should I interpret it? One remark, I know my usb has a lot of broken sectors. Maybe I should just buy a new USB drive?

Thanks in advance!

Never seen this.

You can try the stick, but be sure that the integrity check is successful before installing.

Should it fail: Try flashing again, with enough luck it will work eventually.

However i would strongly recommend buying a new USB-Stick if you can afford it. You will loose data on that eventually.

Tried it again, same command, same iso, same usb stick:

I will buy another usb stick :slight_smile:
Thanks for your opinion.
