--- Begin Message ---Package: coreutils Version: 8.26-3 Severity: critical File: /bin/dd Tags: d-i Justification: breaks unrelated software Dear Maintainer, I wanted to burn a Fedora ISO image to a USB flash drive for testing using the dd command. However, I typed the command into the terminal before plugging the flash drive. dd showed as if it had recorded the data, although there was nothing plugged: ------------------------------------------------------------- # dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb 2813952+0 records in 2813952+0 records out 1440743424 bytes (1,4 GB, 1,3 GiB) copied, 2,30878 s, 624 MB/s ------------------------------------------------------------- After that, I plugged the flash drive and ran the command again. dd shows as if the data had been recorded (same output shown above), but nothing happened. I tried to see if I could list the device using "# fdisk -l" but it does not appear; However, the nautilus file manager mounts the flash drive and displays it with the ISO image label. It is possible to write data by nautilus but nothing happens using dd. After a few failed attempts I went to dismount the USB flash in nautilus but appear the following error message: ------------------------------------------------------------- Error ejecting /dev/sdb: Command-line `eject "/dev/sdb"' exited with non-zero exit status 1: eject: tried to use `/dev/sdb' as device name but it is no block device eject: tried to use `.//dev/sdb' as device name but it is no block device eject: unable to find or open device for: `/dev/sdb' ------------------------------------------------------------- -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=pt_BR.UTF-8, LC_CTYPE=pt_BR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages coreutils depends on: ii libacl1 2.2.52-3+b1 ii libattr1 1:2.4.47-2+b2 ii libc6 2.24-10 ii libselinux1 2.6-3+b1 coreutils recommends no packages. coreutils suggests no packages. -- no debconf information

--- Begin Message ---Hi Klebson! There is no bug here, you are just ignoring the fact that dd works on files, not devices. Hence, if your command is: dd if=bla.img of=/dev/sdb and the device /dev/sdb doesn't exist yet, dd will just create a file with that name which is perfectly fine. The error message that 'eject' spit out is just a result of this. If you run "ls -l /dev/sdb", then you'll notice that your sdb file is missing the "b" flag: root@ikarus:~# ls -l /dev/sda brw-rw---- 1 root disk 8, 0 Apr 20 21:23 /dev/sda root@ikarus:~# ls -l /dev/sdb -rw-r--r-- 1 root root 16375808 Apr 27 09:10 /dev/sdb root@ikarus:~# dd is behaving as expected and I am therefore closing this bug.
