Now excuse me but I have had people saying that sony is very slack and there firmware updates do jack. I have got there latest version of firmware and it still does not burn sd2

so could someone tell me what other firmware is compatible with with 140e ide drive and burns sd2 or at least works with the amplified weak secotrs on cdclone enabled
people recon it burns efm encoding witht he right firmware but I have no idea what firmware would be best to put on it
thankyou
