If this was being added to atacontrol I think I'd want to do quite a bit of work first to make it more robust. However I don't think the code from ataidle could ever just be merged in to atacontrol because the code styles are quite different; however since the interface to the ATA driver is quite straightforward it should be trivial to re-implement or copy the bits needed. -- Bruce
