Created attachment 151961 [details] KDE Partition Manager and GParted side by side SUMMARY I test some bootable isos on an usb stick, when i write an apple formatted iso file that has apple format, kde partition manager does not detect if its gpt or mbr, and it says "no valid partition table was found on this device", but obviously it is exist that i can mount it on thunar and see its content, even if its read only, its working, then i tried gparted, it shows several partitions, i attach screenshot of both kpartitionmanager and gparted to compare. I also added a FAT32 partition on the stick with gparted, kde partition manager still doesn't detect anything, but thunar file manager is able to mount and modify that partition too, i didn't encounter problems with it. STEPS TO REPRODUCE 1. Write an apple format iso file like install disc of macos into an usb stick, using dd or similar tool. I have used mintstick from aur for convenience. 2. Launch kde partition manager, wait for detection finished. OBSERVED RESULT No partition table is detected on the usb stick. EXPECTED RESULT Partition table should be detected and shown as in gparted shows it. SOFTWARE/OS VERSIONS Linux Kernel: 5.15.60-1-MANJARO (64-bit) KDE Plasma Version: 5.24.6 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION I have installed udftools with pacman, because partition manager warned me to download it in order to see partitions on usb stick, but result did not change, then i tried installing apfsprogs-git apfs-fuse-git linux-apfs-rw-dkms-git from aur, also rebooted, result did not change.

Unlikely to be fixed as KDE Partition Manager uses sfdisk to detect partition table and as you can see fdisk does not detect it. In particular, we run "sfdisk --json /dev/sda" and look for device type. Maybe you could actually run this command and see if it prints anything useful?
