I have an Asus crw-4816a 1.12. I downloaded ver 1.05 bin format teac cd-w548e firmware. I flashed my drive and it works!!!! The sound the drive makes is lesser, the tray opens more rapidly and finner, i can now read cds that i previously couldn't. Isn't that amazing. And, in nero 5.5.80, the buffer underrun prevention option was Burn-proof. Now, with newer versions it is FlextraLink. And more importantly, the writing quality has immensly improved!!!! Isn't that absolutely amazing? I recommend anyone who has the asus crw-4816a to flash it to teac cd-w548e. At least until asus releases a new firmware, because i saw it released a few days ago a firmware for the asus crw-4824a and they say it greatly improves media compatibility and writing quality with certain media.
