This question is somewhat related to the previous question I asked regarding the dd command, The dd command isn't appear to accomplish anything.

I'm trying to burn the Ubuntu operating system onto a USB flash drive, so that I can boot from it. Currently I'm getting this output like this when I attempt the burn:

dd: reading `ubuntu-14.04.3-desktop-i386.iso': Input/output error
1280+0 records in
1280+0 records out
655360 bytes (655 kB) copied, 0.04214 s, xx.x MB/s

For reference, I'm running the following command:

sudo dd if=ubuntu-14.04.3-desktop-i386.iso of=/dev/sda1

To clarify:

  • I know that /dev/sda1 is my USB stick.
  • I'm running this on a Raspberry Pi, running the Debian distribution.

  • Can you read the SD card? That is sudo dd if=/dev/sda1 of=/dev/null. – Brian Oct 10 '15 at 22:04
  • is the iso located on /dev/sda1? – mikeserv Oct 10 '15 at 22:06
  • @Brian Yes, I can read the USB drive. – Ethan Bierlein Oct 10 '15 at 22:07
  • @mikeserv Yes it is. When I run the lsblk it tells me that it's the case. – Ethan Bierlein Oct 10 '15 at 22:08
  • /dev/sda1 is a partition, not a drive. Or at least, it should be. What does sudo fdisk -l /dev/sda print? – The Sidhekin Oct 10 '15 at 22:11

Well, it seems that I really don't understand a lot of basic concepts about this stuff. Turns out I was trying to burn the Ubuntu disk image, while it was contained inside of my USB flash drive. All I had to do was move the file to a different location, cd there, and continue with the dd command.
