Repair corrupted PDF files after recovery

Hello all!

I accidentally deleted a PDF file (and emptied the recycle bin) and several days later used recover software (RStudio, plus two others) to retrieve it, but it was overwritten (according to one of the programmes).

Now the file has the right name, the correct size and the correct time/date stamp, yet it wont open in Adobe because 'it is either not a supported file type or it has been damaged' (according to the Adobe error message).

Is there anything I can do? I've tried changing the file name, then opening it in txt/notepad, doc/Word, but no luck.

I downloaded some demo version PDF repair tools (PDF Fixer, Recovery Toolbox for PDF) but they say that 'no PDF data has been found' and lists 10 errors (though wont say what they are).

I am really anxious to get this file back. Could you please advise me? Many thanks.

This sucks and is why we do backups. You can try to retrieve the data using a HEX editor. It will show the data in its raw form so that you can try to salvage the text.

Other wise the data is gone. There is nothing to restore because there is nothing there. It got over written. You could take your drive to a data recovery shop where they try to do a layer read from the drive and reconstruct it but this very costly. How important is this file?

Here are some repair tools for PDF....

Also there is Helix which is a forensic tool set that might be able to recover the deleted file but you really need to know what you are doing to use it and is why the data recovery shops cost so much because of their training.

Good Luck.
