Yes, as dd gives you an 1:1 copy of what you have. If you intend to "experiment" on the partition (which means that you don't just do reading operations, but writing operations, too), and you're using FreeBSD for that, simply use dd's of= parameter to write to a file instead of directly to the partition; format the ad12 disk with UFS for that purpose. > Should I zero out the 250g drive > first? No need, as dd should overwrite anything. > Can "ddrescue" do a better job? The ddrescue program has the ability to adjust reading block size dynamically if reading errors occur. As you said, the disk itself seems to be fine, so no job for ddrescue here. > The Docs&Sets folders > are the most important to recover so if I can access the data, I can > burn it to DVD.
