You will get all your data back.
Please make sure you are using the latest version of Recover My Files, currently 3.80 and avaialble from
www.recovermyfiles.com.
In your situation you should first try the Format Recover options - because there is a problem with your drive. A "Fast Format Recover" should be tried first (as it will only take 10 mintues to run).
Depending on the results, then try a "Complete Format Recover". Only search for the default selected file types, and do not include multimedia for music files in the search as it will slow the search down. At the end of the search the program will use the default file types to rebuild the entire partition and you will have access to all your deleted files, will full file name and folder structures. The search should take no more than 10 hours to run to completetion.
