Dd Input/output Error Dvd
Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Interpreting dd Input/Output error up vote 4 down vote 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 "dd: /dev/rdisk3: input/output error" 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 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 47.6k1462125 asked Aug 16 '15 at 0:08 Scoopta 304214 (1) Please show the command(s) that you typed to get this output.  (2) Do you know how big you disk is?â€

The hard drive I am trying to copy is formatted ntfs and has XP on it. It is about 6 years old and is having problems. When booted from a 10.4 live CD. Most of the time the hard drive reports that it is not a S.M.A.R.T. capable drive. Once, it was, able to read the SMART data and reported OK except 3 bad sectors. From the above and especially the "smart / no smart" I am assuming that there is likely a controller problem on the drive as well as the bad sectors. dd exits with the following error :- Code: ubuntu@ubuntu:~$ sudo dd if=/dev/sda1 of=/media/Iomega\ HDD/backup/pc130111.img dd: reading `/dev/sda1': Input/output error 6406224+0 records in 6406224+0 records out 3279986688 bytes (3.3 GB) copied, 432.584 s, 7.6 MB/s ubuntu@ubuntu:~$ The windows system still runs, but its time for an .img and a new drive, before it dies. What do I need to do here to get a usable copy of this drive ? Ibod.

However, my raspi (which I runs off of this dd input/output error 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 6,1391165127 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=noerror parameter. This will replace bad blocks with zeros, and if you dd that image back to another same-size card, it should work the same. share|improve this answer answered Oct 19 '13 at 19:34 mvp 47.9k85391 1 I already tried that and it still does not work. It gives more or less the same error, but many more times –puk Oct 19 '
public IPaddress Recovering a non-readable disk on Mac OSX 2013/01/13 nbalkota Mac 84 Comments Today, as I intended to perform my regular Time Machine backup, I got welcomed by a very scary message when I connected my external hard disk to my MacBook. The disk you inserted you inserted was not readable by this computer. Now, I take pride in having never ever lost any data on my Macs since 1998, so I was concerned this might be the end of my record… In Disk Utility the drive device was listed, but no volume could be mounted due to a corrupted partition map. Don't ask me how it got corrupted in the first place. I would guess the disk never liked incident when it got unplugged without using the eject command… Anyway, salvation can come at no cost by using the Terminal in Mac OS X (assuming you have administrative rights): Connect your external disk Start terminal and use the 3 commands in bold red below If the last command was successful, disconnect and reconnect your disk, which should now be OK IronMan:~ nbalkota$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *250.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS IronMan 249.2 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.0 TB disk1 1: 0xEE 1.0 TB disk1s1 IronMan:~ nbalkota$ sudo gpt recover /dev/disk1 WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files.

Password: gpt recover: /dev/disk1: recovered primary GPT table from secondary gpt recover: /dev/disk1: recovered primary GPT header from secondary IronMan:~ nbalkota$ diskutil eject /dev/disk1 Disk /dev/disk1 ejected An alternative to the second command (gpt) would be diskutil repairDisk /dev/disk1 Note than the manpage for gpt does not cover the recover option whereas the manpage for diskutil does cover the repairDisk option.

I did the "diskutil list" command. and then i did the "sudo gpt recover /dev/disk1" command. then it asks for my password. does it mean my computer password? or is the password the third command "diskutil eject /dev/disk1"? either way once i get to that step it won't let me type in any password. i type and nothing appears. the
