@PrivateVoid: Does your Asus Notebook come with a HL-DT-ST GSA-T50N SATA DVD drive? (Run command "sudo hdparm -I /dev/sr0" to obtain this information)

I had a discussion about mine (Asus B50A Notebook) on the linux-ide mailing list. They came to the conclusion that the problem I am seeing is a firmware issue of my SATA DVD drive.

See this thread for reference:

My drive uses firmware revision RR04 and I am currently in the process of trying to obtain an update from Asus. The manufacturer Hitachi LG Data Storage does not provide any firmware updates for its drives (http://www.hlds.co.jp/e_HLDS/faq.jsp).
