Thank you very much Jarad and datahaze for your advice.
But after reviewing how to use dderescue I think it may be too advanced for my level of ability, especially since I have no knowledge of Linux. I think I might have to spend more time learning how to use it and assembling the necessary tools than actually recovering the data. And I am afraid I would make a mistake since I am so unfamiliar with everything. It scares me. I'm sure it must be an excellent tool, but it seems too advanced for me.
