This problem has been discussed before and it seems there is no solution for the MSR file. Even if you recover the files, the Secret Zone will still need to the same intact partition. There is no information about a possible recovery file to use to access the files in the MSR archive. Try to avoid writing to the HDD and make sure you have the MSR file to a safe place then contact your local Samsung supplier, reseller, technical support, etc. You should obtain information related to this error. They're the only ones that might have a solution.
