@DarkMahesvara Filesystem based checksumming and ECC RAM will reduce the error rate a huge amount, but as far as I'm aware, there is still a slim, but not "basically impossible" chance a triple RAM bitflip occurs (undetectable by ECC), or one while the data travels down the memory bus into the CPU and into the cache (I'm pretty sure there's error checking for memory busses, but not cryptographic grade I believe) - or qbittorent had a bug and didn't actually finish the download.
