Up until 2011 those discs had been dumped by HwitVlf, huygens, iR0b0t, osam and pepsidrinker and were verified.
In January of 2011, the dumper Nakian was added but all hashes changed. In 2019 the dumper superg was added verifying the new hashes.
What happened here? Were the previous dumps faulty for some reason? Or were the dumps by Nakian and superg another revision that were erroneously added to the original dumps?
