You have wrongly guessed about the cause of your problem.

A problem with the MBR would not prevent RStudio etc. from finding data during a raw scan.
The error message you see about "disk not formatted" can have several different possible causes, but a problem with the MBR is rarely involved.
There are other tests you could do (if you accept the risks of DIY!), but it is clear to me from the thread so far, that I would have some communication problems with you. Therefore I politely suggest you work with a local DR company to remove those communication issues.
