Erhm, I would get a new disk :), you dont intend to trust any
data to this setup do you ??
Anyhow, I dont remember if it is possible to actually get at the data on
a transfer that the drive marked bad, but I can check up when I get
to my doc shelf. But I wouldn't trust that data for _anything_ it is
likely to be totally corrupted due to the drive trying to ECC correct
it and what not...
