I began the Recuva scan about 2 hours ago. The first drive scanned in about 30 minutes. The second drive has been scanning for 1.5 hours and the progress % just keeps increasing and is at 17450% the green progress bar goes to full then starts over continually. The estimated time rapidly changes from 33 days, 7 days, 5 days, 1 day, 41 days, 11, days and just keeps changing rapidly. Should I just let it run?
