Hi,
It is actually very difficult to know exactly what has happened to your FAT table without conducting a full forensic examination. To do this, we would need access to a bit image copy of the drive.
Scandisk can cause many different problems, depending on what it was up to when the process was interrupted.
I suggest you download Recover My Files from
www.recovermyfiles.com and run the program in evaluation mode.
You should try a "Complete Format Recover", and search the "physical drive" only for the default selected file types (this will make sense when you run the program and follow the wizard steps). At the end of the search the program will rebuild the old FAT, and you should see all your files and folders with full file and folder names in "Folder View" of the results screen. Click on the files found to preview their contents in the preview window. If you can see the files (read the documents and see the pictures) then you know the files that have been found are valid and can be saved once the program is activated.
Please post here and let us know how it goes.
Thank you.
