I'm running Recuva on a 1TB external HD. I've been at phase 1 for about 3 hours now. Within 5 minutes, it found 1350 files. Scan progress is at over 4500% and no more files have been found. Is this normal or am I stuck in a loop. Estimated time left is jumping around from 40 days to 3 days and every number in between. Please help.
