I had the same errors on Ubuntu 14.04 64Bit. usb-creator would fail to erase ext4 formatted pendrive. I re-formatted to FAT32 (using mkfs.vfat) and was able to successfully create a Live pendrive (with no need to erase using usb-creator). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305020 Title: Startup Disk Creator fails to clear USB drive To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1305020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
