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 47.4k1462125 asked Aug 16 '15 at 0:08 Scoopta 167114 (1) Please show the command(s) that you typed to get this output.

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.

The dd input output 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.

While the corrupted data won't hurt the new drive that it's transferred to, it could bring varying i

It failed to read some sectors, while working ok otherwise. The following text shows, how I recovered the filesystem. A couple of years later Florian Hackenberger pointed out, that dd can cope with read errors if you supply the correct options. So you could also use something like: dd if=/dev/hdc1 of=disk.img bs=512 conv=noerror,sync. Even more comfortable rescue is possible with the specialized tools ddrescue or dd_rescue. My completely manual method I got myself a second computer with a big empty harddisk and a running linux. I installed the broken HD on the secondary IDE channel. My plan was to get a raw image of the main partition, mount it again with linux's loop option and copy the data onto a new HD. The broken HD is /dev/hdc . Partition 1 is the / file system. Partition 2 was my swap device. I read in blocks of 1024 bytes. [root@base /tmp]# dd if=/dev/hdc1 of=1 bs=1024 dd: /dev/hdc1: Input/output error 7332+0 records in 7332+0 records out The first part of the disc was read. Obviously the 7333th sector of the HD is damaged. I tried a dd if=/dev/hdc1 of=tmp bs=1024 skip=7332 count=1 and got the IO error again. So we just skip this sector and proceed with the area after. [root@base /tmp]# dd if=/dev/hdc1 of=2 bs=1024 skip=7333 dd: /dev/hdc1: Input/output error 385907+0 records in 385907+0 records out We encountered another broken sector. We just skip it. Be carefull about the new skip value. You have to sum up all previous skip values: 7333 + 385908 = 393241 ! [root@base /tmp]# dd if=/dev/hdc1 of=3 bs=1024 skip=393241 1219527+0 records in 1219527+0 records out Now we finally managed to read up to the end of the HD. Now we have three pieces each with a hole of 1KB. Now we make ourself 1K of plain data. [root@base /tmp]# dd
