I've been trying to find out more about a drive in my HP desktop - IDE-DVD DROM6216.
Have found entries in this site and the HP site that confirm this is a Philips drive.
Have also found a comment that says a firmware upgrade from Philips may not work in a HP machine - so beware if you decide to upgrade.
The latest update for the drive that I have found, on the HP.co.uk website, just happens to be HD08, which is the same as you and I have so suspect a further version is not yet available.
For anyone that needs this version you can find it here : http://h10025.www1.hp.com/ewfrf/wc/genericSoftwareDownloadIndex?cc=uk&dlc=en&lc=en&softwareitem=pv-32000-1&jumpid=reg_R1002_UKEN
