As stated in the topic I have an old xw6200 Workstation with 2 Xeon 3.2Mhz processors with Win7 64-bit, SCSI board, Nvidia Quadro graphics card, 8GB RAM and two optical drives, one of them CD/DVD-RW.
Early I realised none of the optical drives were functioning inside Win7 environment, neither were recognised its icons.
However they work correctly when I boot some tools from a CD/DVD, and the BIOS identifies them as well.
The Workstation was bought with no OS installed.
I partitioned the HDD, and the System worked very well with Win8 and Win7 in Dual Boot during several years, reading and writing CD/DVDs. Until I realise optical drives were not detectable in both OSes.
Was it due to an automatic update of the drivers or any security inhibition (Windows Update)? I don't know.
I tried to solve this issue of the System (both Win8 and Win7) using the official HP drives. No update was capable to solve the issue. The message appearing was sort of 'The drive installed is up to date'.
After many hours, I formatted the HDD and tried to restart a clean installation.
Neither WinVista 64bit, neither Win7 Ultimate 64bit, neither Win8 Professional 64bit (none of this versions are OEM) were capable to proceed. In all the tries, at the begining, appeared the message 'CD/DVD driver is missing'.
I didn't try Win10 just because the machine or its BIOS does not support it. I know Win8.1 was not possible to install by Microsoft Store due to incompatibility issues, when the machine was fine.
So, the problem remains: I need the drivers for optical drives "HL-DT-STDVDRRW GWA-4166B" and "HL-DT-ST RW/DVD GCC-4481B".
Without them the machine is useless.
Can some technician help me please? I would much appreciate it!

Until now there are no solution for my problem here...
Meanwhile I reinstalled in dual Boot Win7 and Win8.
Again, none of the OSes identify the optical drives.
I wonder why HP has an exclusive policy to grab customers for its own products, as it is impossible to solve this issue without any workaround apart of HP Technical Support!
HP is not any big Apple with exclusive hardware, but tries to pretend so.
Even RAM memories are a headache, just because there are severe compatibility issues between HP boards and third party boards.
In a mathematical sense, there is no biunivocal policy regarding compatibility among HP and third party Hardware!
Someone told me, in a private message, I have to call for assistance using HP technical support by phone to (try to) solve my issue.
Well, since I live in Portugal, not in US nor Canada, I have a problem!
And I know Portuguese HP technical assistance is lousy!
That's why I use this Forum in English.

DGroves gives good advice. We are not HP techs here.... this is a user-to-user forum so he and I are just like you, with more HP workstation experience, however.
Here's a little input..... the xw6200 was from the series before the xw6400 came along, and I started with that one. The xw6400 workstations usually came with ATA optical drives, with the big flat ribbon cable pluggin in the back, and things like master and slave jumpers. However, one can use a SATA optical drive in these workstations and just leave the ATA ribbon cable unplugged.
You'll need to get a SATA drive cable that is long enough, and a SATA optical drive (very inexpensive). Then try that as a "plug and play" device. Download your technical and service manual for the xw6200 from here: http://jp.ext.hp.com/lib/doc/manual/workstation/hp_workstation/c00213035.pdf
In that workstation you only have two SATA ports on the motherboard, SATA0 and SATA1. Plug your SATA HDD or SSD into port SATA0 and the optical drive into port SATA1.
There is a limited number of drivers that Microsoft can have on the system installer CD/DVD so you seem to be using ATA optical drives that are either unrecognized.
Computer shops have a bunch of these SATA optical drives laying around. They don't get used much so they rarely go bad.

SDH,....note that he says the optical drive does work if it's booted from implying a working device
it's windows that does not see the drive and this was usually caused by the corupted filter driver registry entrys i mentioned
however your advice about SATA CD/DVD drives is a point i failed to mention you are correct that it's best to replace a PATA device with a SATA device where it's possible as they are usually cheaper, easer to find and based on a later spec/standard
also a bad/defective windows install cd can also cause problems if possible try another install disk
last, the xw6400 and most likely the xw6200 does support booting from USB, so you can download the win 7 install image then use "rufus" to create a bootable image of the cd on the USB key

i also forgot to mention that the message '"CD/DVD driver is missing'" can appear when trying to use a USB 3.0 device
as the install device (such as a USB key or a external cd/dvd drive) connected to a addin usb 3.0 card as windows OS's up to 8.0 do not have built in usb 3.0 drivers
the workaround is to either use a usb 2.0 port or the "F6" key for win 7/XP to load the missing usb driver
note thatwin 10 does not support the add driver via F6 option
