Recuva worked fine and detected the excel file I was looking for but sadly said the file was 'unrecoverable'. Of course I asked it to recover it anyway and it gave me an excel file which could not be opened. However the file is 18 kb so is it likely to contain some of the original data or will it contain a fragment of what overwrote the file when I reformatted? Is is worth trying to open the file?
