I've had this problem also. What I was able to do in my case was to create two images of the drive. One image was the space prior to the error and the other was the space after the error. I was then able to generate a valid matching hash on the entire drive with the exception of the bad blocks.

Hi all. I'm trying to properly clone a 4.3GB (it's old, I know) hard disk which unfortunately has a lot of bad sectors. I am using Helix 1.7 as an operating environment, not mounting the old drive at all. I used the command: dd if=/dev/hdb of=/mnt/hda7/image.dd conv=noerror,sync My problem is that the md5 hash of the image file is different from that of the original HD (acquired via the command: dd if=/dev/hdb conv=noerror,sync | md5sum > /mnt/hda7/orig_disk_md5sum.txt) Can anyone please enlighten me as to what I'm doing wrong?
