As long as it reads the data and sends it through without any attempt at "correction", it should be fine. But if it is trying to do correction on the fly, it'll probably mess up AccurateRip.

I bought Pioneer because of its advertised Pure Read 3+, but if this comment is true then it's worse than normal drives because it messes up AccurateRip? By the way does EAC have AccurateRip too like dBp? Would this mean that Pure Read wouldn't work good on both EAC or dBp?
