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 /dev/sdc1 /dev/sda1 | pv share|improve this answer edited Sep 27 at 22:47 David Foerster 10.6k93052 answered Feb 9 '13 at 13:26 Dennis Kaarsemaker 4,9741432 yes i said that but restoring from backup it's on that drive.. and i this drive have only sector problem, well how can i use that command? im just newbie linux user.. –Erazer Feb 9 '13 at 13:31 2 So your backup is on the same drive as

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. Adv Reply January 13th, 2011 #2 GNU-Cody View Profile Vie

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 if=/dev/zero of=z bs=1024 count=1 1+0 records in 1+0 records out Now we copy the files together and we have a nearly perfect image of our broken HD. [root@base /tmp]# cat 1 z 2 z 3 > hd We should now run fsck on the image, because there will be at least 2 errors resulting from those two 1K holes, which we filled with 0 values. [root@base /tmp]# fsck.ext2 -a hd hd contains a file system with errors, check forced. .... with some repair msgs from fsck We now can mount this HD image to /mnt/old. [root@base /tmp]# mkdir /mnt/old [root@base /tmp]# mount hd /mnt/old -o loop Our new HD
