Hi, No problem for opening a bug for this, but what do you mean by "creating a dump with a hex editor"? Could you provide me some guidelines to do that or point to a resource where it is explained? Thanks! Pierre Le lundi 26 juin 2017, 22:06:53 NZST Carlos E. R. a écrit :

Hi,
Just to let you know that I could reproduce using the following protocol.
1- Download the Leap ISO, I used the NET install image from: https://software.opensuse.org/distributions/leap 2- Plug a USB key and copy the ISO on the USB key using: sudo dd if=/home/pierre/Downloads/openSUSE-Leap-42.2-NET-x86_64.iso of=/dev/sdc bs=4M status=progress && sync 3- Unplug & Replug (probably not necessary...) 4- Open Gparted, remove partitions on the USB key (don't touch the partition table!), create a new one in FAT32, put a label of your liking (say "MYLABEL"). This was a bit brutal and not cautious, but it creates roughly what you need, a formatted USB stick.
This result in the following different behaviour in Leap and Tumbleweed: - In Leap, when you plug the USB stick, Plasma reads a USB device named "MYLABEL" and mount it without problem. Gparted sees it as a FAT32 partitioned device, as does fdisk. - In Tumbleweed, when you plug the USB stick, Plasma reads a USB device named "openSUSE-Leap..." and can't mount it. Gparted sees it as a ISO9660 partitioned device, but fdisk sees it as a FAT32 partitioned one.
Perfect! You could write a Bugzilla with that precise information, it is enough. :-)
If you look at a dump of that USB stick with a hex editor you will see the ISO label somewhere near the start. Some of the structures of the ISO were not overwritten by gparted when formatting as FAT. I don't know if that data is in the first sector (the partition table) or further on. My guess is further on.
That's all I could think about. I'm keeping the USB stick as is if you want me to run some more tests (Leap I can do only at work during the day).
Maybe extract a 1 MB dump, verify the above, and attach to the bugzilla.
I see two bugs or problems:
- not clearing of the ISO structures by gparted - incorrect identification by TW.
