It keeps on getting stuck at stage 1 of 3, 9%, 4 days remaining, 78486 files found on a 1TB external drive. It's been running for over 24 hours now. I've checked the power settings to make sure that nothing is disabled for power saving. Task manager shows fluctuating cpu usage for the Recuva process. I've tried rebooting. I paid for the professional version so I expect it to work. The free Piriform version always worked like a charm, so I'm surprised that the paid version is so terrible.
