You can try ddrescue, it may be able to work around the broken path. Beware though, that you will lose data.

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.

However, my raspi (which I runs off of this SD card) runs fine (ish) and Disk Utility claims that the sd card is not corrupted. Is there another way I can find out why dd is complaining, if the card is corrupted, and if so, how to fix the SD card. UPDATE: I gave up trying to run dd on the SD card, but I did figure out what was corrupting my SD card, it was the updating of the Raspi firmware as specified on this site backup dd flash-memory share|improve this question edited Oct 21 '13 at 22:34 asked Oct 19 '13 at 19:28 puk 6,1091165127 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote It is possible that your raspi simply does not hit badblock on your SD card, and that's why it appears to work fine. You can dd image and ignore bad blocks by adding conv=no
