I had the misfortune, after backing up to my WD Passport my files prior to undertaking a Windows repair, to find that for no apparent reason the files had vanished from the drive.
Using a recovery utility the files are now ready for re-saving to my main hard disk. However a minority are now gibberish ( word, excel, pdf files mainly). I assume some thing has happened to encoding. Is there anything I can do to restore thsoe files to their proper states? In the case of some word/ excel files a error box as in the attachment showed, but none of the options I chose effected a cure.
I'm in need of rescue!!!
