Hi,
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) [etc]
You might need to specify obs=<something>. If dd uses different
output block sizes in the two cases the amount of padding in the last
block will be different and so will the digest.
