If the data is important to you, go out and buy a new drive and use dd
from that broken drive to the new one (nothing there to erase). Then
afterwards reformat/partion the new drive and use it as spare storage
space (eg backups!).

When a hard disk fails, it fails. The recording medium is scratched, the
rust (iron oxide or ferrite) flakes off, etc. It is IMPOSSIBLE to
recover the data there. dd can be told to ignore errors, on blocks, and
just go on to the next one. cp cannot.
