Sorry to revive an old thread, but a forum search did not reveal this answer:
The DS-8AZH 03c is a Philips & Benq Digital Storage Corporation drive. Can’t find anything that gives a non-HP # on it though.
I pulled the one from my DV6326US which I got back in September. The drive was made in Feb 2007. F/W is NH61 and H/W is 01. DHHS factory ID is GZ. HP part # is 416179-HC0.
To remove the drive from a DV6000 series machine, remove the screw just behind the battery latch (right by one of the memory/mini pci-e slot screws) and the drive will pull right out. Probably a good idea to pull the battery first, HP says to open the drive tray and use the tray frame to remove it. With the wrap-around bottom of the faceplate, I was easily able to pull the drive with it closed.
The HP maintenance/service/parts manual is downloadable from:
If the link doesn’t work, go to the HP homepage and search for “maintenance and service guide dv6000 series”.
The manual lists all parts, shows a mechanical drawing of the machine, and gives complete step-by-step disassembly instructions.
(edit to add: )
I haven’t used the drive a lot, but I’ve written a few CDRs (RiData), read several CDs and DVDs, ripped a couple of DVDs (started and walked away so I didn’t time them, but no 8X drive can rip like a 16X desktop drive), and burned a couple of +RWs (HP with a Philips MID - burned ok, and my NEC 6500A wouldn’t even write them without an error).
