[linux-lvm] Can I dd one disc of a lv

  Use dd_rescue instead. That tool is developed to be better than dd
  for copying data off bad drives. dd_rescue can also walk backwards.
  If your system freezes when reaching bad blocks then you can write
  down the block and tell dd_rescue to copy the disk backwards up to
  that block.
