I have not now that you've mentioned it, but it appears that my PCs lost power during the night so didn't notice anything until the morning when I wanted put some files on it, it's been running for a good while(~4 hours done and ~2.5 hours to go) with zero errors so far. But does that mean I'll have to rerun it one more time without parity correction and see if I get a different result since shouldn't just seeing the errors found be enough?
