I too encountered the same thing. I had one of my WD external hdd failing, and now I have to recover the whole disk on 1,5 TB. It was slow to start with, but suddenly it went faster. Now though, it have been stuck at 83% for 3 days, and I am afraid it can't go any further. Has anyone got any suggestions on what to do now? If I abort, will I be able to recover what it has found, or will it just abort without showing any files to recover? The program has been running for a week now. The program is great. I got the feeling that it's the disk that stops recuvca from getting any further..
