Most linux distros provide hybrid iso files, which work both to create DVD boot disks and USB boot drives. This means that there will be an iso 9660 file system in the USB drive.
This is not wrong, it is a working system for a live-only drive and installer drive. The problem is that some tools do not understand, what it is, and complain, that is is corrupted. Fortunately there will be a new version of gparted in 17.10, which can recognize such drives. ** Attachment added: "lsblk-and-gparted-seeing-iso9660.png" https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1708881/+attachment/4971656/+files/lsblk-and-gparted-seeing-iso9660.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708881 Title: USB Stick corrupted - The driver descriptor says the physical block size is 2048 bytes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1708881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
