Image doesn't pass media check if Fedora Media Writer is used

[polovest (John)]

I don’t know why, but if I use the official Fedora Media Writer for Windows to write a Fedora .iso to my USB sticks, they won’t pass the media check later:

I used two different USB sticks, they are okay. If I use Balena Etcher instead, the checks do pass.

That’s been my experience for a while on Windows (Media Writer would sometimes write fine though) and I also use Balenca Etcher.

Media Writer produces USB stick with FAIL media check

@polovest

If I use Balena Etcher instead, the checks do pass.

Or the check is just skipped. When the entire USB device doesn’t look like an iso9660 file system, the check will be skipped. If the USB device is inserted and located at /dev/sda, for example, you can run checkisomd5 /dev/sda to see if the check really passes.

I think it is a known bug

Install media sometimes fail media check at 4.8%

Problem After creating a USB installation medium and trying to boot it, the included “media check” started during boot might report an error at 4.8% and announce that the media is corrupt and shouldn’t be used, even though the media might be technically just fine. [media-check-fail] Generally, when seeing this image, you can be fairly sure that the image is really corrupt and you should verify the checksum of the downloaded image (if you downloaded it manually) and try to create the USB mediu…

It occurs with the latest F41 images and with the F42 images.

I did not know it was only with Fedora Media Writer. You may want to make a note of it on the common issues page.

For note, I use ‘dd’ to write disk images.
