It now appears that your problem is much more complicated than your original post implied. I cannot help you because I do not know anything about SSD technology and cannot infer enough from your post. If no one else can help you at this point, your next step should be to find and post a link to documentation for the applicable technology. Then update you example using the exact vocabulary of the reference for function and variable names. Tell us clearly what data you have recovered and what you have to recreate. (Are you even sure that this task is possible?)
