Hi Augeas,
I cancelled the scan and a huge list of files were displayed. It included many of the file types I was hoping to recover, such as CRW (Canon raw files), psd files, jpeg's, tiff's, etc It stated that every file was in excellent condition and not overwritten. See screenshot below of the results;
I re-launched Recuva and did another scan with the settings you advised, i.e. Scan for Non Deleted Files and Restore Folder Structure checked. The other boxes in the Action tab were left unselected.
The result finished virtually instantly with just 3 files shown, as seen below;
Any ideas on how I can recover the files shown after the deep scan, but preferably keeping the folder structure and names intact?
