I don't sure about anything :) For example - my Panasonic 572B doesn't need any delays at all.But GoldStar does.So i don't realy know which one are neccessary and which not :( Also IMHO this delays will not make things worse - may be they will help someone ... But if you whant to probably profile this patch - you can try to delete all DELAYs that are not in atapi_probe(). Alexey Pialkin
