Dd Input Output Error Dvd
favorite I tried to copy /dev/Storage/Storage (an LV under LVM) to an image file using a dd | pv | dd pipeline. dd reported an error, and I want to know whether dd finished copying my disk or stopped due to the error. I'm not sure since it gave me two different outputs: one with an error at the top and one without. I'd take a guess and say it didn't because between the two there's only an extra 0.1 dd error reading dev sdb input output error seconds and no extra data, but I'm not sure if it did or not. /dev/Storage/Storage is a 1 TB disk (terabyte = 1012 = 10004) or 931.51 GiB (gibibyte = 230 = 10243) or 1953513472 sectors. The filesystem on the disk is messed up and doesn't work properly. $ sudo dd if=/dev/Storage/Storage | pv | dd of=Storage.img dd: error reading ‘/dev/Storage/Storage’: Input/output error ] 1627672400+0 records ins] [ <=> ] 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181 s, 11.1 MB/s 776GB 20:53:01 [10.6MB/s] [ <=> ] 1627672400+0 records in 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181.1 s, 11.1 MB/s linux dd share|improve this question edited Apr 27 at 15:26 Anthon 47.4k1462125 asked Aug 16 '15 at 0:08 Scoopta 167114 (1) Please show the command(s) that you typed to get this output. (2) Do you know how big you disk is? Please do not respond in comments; edit your question to provide the requested information. –Scott Aug 16 '15 at 0:36 One obvious question is whether your disk has 1627672400 sectors or not. Try blockdev --getsz /dev/whatever. If you copied the right number of sectors, then you are probably okay. –user3188445 Aug 16 '15 at 0:39 @user3188445 taking that as a no it didn't finish because it's 1953513472 sectors. –Scoopta Aug 16 '15 at 1:26 @Scott I updated my question but it's looking like it didn't finish...which means another 20+

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 6,0941065126 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 block

You can try ddrescue, it may be able to work around the broken path. Beware though, that you will lose data. Restoring from backup will be easier :) The correct usage of ddrescue is as follows: sudo apt-get install gddrescue sudo ddrescue /dev/sdc1 /dev/sda1 or if you want to pipe stdout to the progess monitoring tool: sudo ddrescue /d
