Ddrescue Help

I have an external hard drive of 1Tb which stopped working. I'm trying to recover the information using ddrescue but I don't see anything been recovered. I'm doing the copy from the external harddrive to another one, but it has been more than a week and I dont see anything saying that information is been recovering. Should I stop?. THis external harddrive has important information https://www.hamishmb.com/forum/images/smilies/icon_e_sad.gif. Any advices?. IN the image it says 2 days but my laptop restarted so I continued the process from a mapfile.
