Hello to everyone.

I have built a PC that I use as Videorecorder.

Board is an ASRock Q1900TM-ITX with latest UEFI-Version: Q1900TM-ITX P1.50
Memory 8GB DDR3-1333 from Kingston
Disk is a SSD SATA III disk from Intenso with 240 GB attached to first SATA port
Have installed WIN7 Home Premium 64bit (since I had no internal DVD available  I installed it
via external  USB-attached  DVD burner).

Then I bought and installed an internal DVD burner  and attached it to the second SATA port.

The drive shows up in the UEFI setup and in Windows as well with correct type information.

Problem is, the DVD burner cannot read or write any Type of CD or DVD.
I first encountered the problem under Windows and then tried to boot from my Windows
installation DVD which reads the DVD before the installed Windows is invoked.
This did not work, so I can be sure that it is not a Windows problem.
Then I installed the DVD burner in a different PC where it could read and write all Types of CDs and DVDs with no problems.
My conclusion: I have a problem with the board or it's UEFI setup.
Strange thing is, the other PC has an ASRock board installed with matching UEFI setup (where possible) so ASRock can support this DVD burner but not with my Q1900-board.

Any help/advice greatly appreciated

Please list out all the hardware using Make and Model or P/N that your system is comprised of, including the external power brick.



Also, please check that the internal ODD's data and power connections are firm and secure.

Comparing your other PC where your DVD drive works with the Q1900TM-ITX board is not automatically an equal comparison. While we have no idea what mother board the other PC has, the Q1900TM-ITX is an SOC (System On a Chip) type processor, that has the SATA support built into the CPU itself, rather than provided by the board's chipset. The Q1900TM-ITX does not have a separate chipset, it is part of the CPU, and simpler than other Intel board's SATA support.

I read a user review of this board, and the owner said he used a DVD drive with it and it worked fine.

Did you try trading the SATA data connections on the board, putting the Windows 7 drive on the second SATA port, and the DVD drive on the first SATA port?

But, you can see the DVD drive in the UEFI/BIOS, and it appears in Windows Device Manager?

What is the SATA mode set to in the UEFI? The default AHCI option?

Intel does not provide a SATA driver with this system, so it must use the standard Microsoft storage driver. You have a Device Manager entry that is, ATA/ATAPI Controller? If so, what is the driver shown in the Driver tab of the Device Manager Properties?

Since the DVD drive works on another PC (with Windows 7 in the other PC?) then you might have a driver issue with the Q1900TM-ITX.

Hello parsec.

-Yes I traded the SATA data connections with same (bad) results
-Yes I can see the DVD in UEFI and WIN device manager
- SATA mode in UEFI is AHCI
- ATAPI controller in device manager shows microsoft driver 6.1.7601.18231

But as I wrote, booting from DVD (before Windows boot, loading device drivers)
which is a hardware thing (considering UEFI belonging to hardware) does not
work, so it is not a Windows device driver problem.

By the way, the other PC has a FM2A88X EXTREME4+ board from ASRock installed,
and there, as mentioned, the DVD burner is working properly.

What power brick are you using with the Q1900? To me it sounds like it isn't pushing out enough power for the Optical drive. If the drive is detecting but failing to read/write (known good through testing on another system) then it may be that when the drive tries to spin up the extra power load is causing the drive to reinitialize in a loop. If the disk appears to spin up, stop then spin up again repeatedly then this could well be your issue. Different brand and model optical drives can behave differently but in general an initialization loop will spin up, spin down, indicator light will flash with disk spun down then spin back up again with some indicator LED activity.

I have seen this happen with bad PSUs and improperly seated power connections over the years. Given this is a DC jack powered board that would be my first suspect.

Hello Xaltar,

yes the board is powered by a delll power brick I had from an old Dell Inspiron notebook.
It  is a HA65NS1-00 model with 65 Watt power.
I can do a measurement of the input voltage to the board while the DVD burner is spinning
to see if your assumption applies, the voltage should drop down somehow  !?
In the manual I did not find any information how much power the board needs and
I thought 65 Watts to be enough.
Since I am on retirement it is hard to find the time to do such things Wink
We will see ......
In the meantime thanks to all trying to help me.

It is the only thing that makes sense in your situation. If you read earlier in this thread you will see Wardog also asked about the power brick.

When an optical drive begins reading it's power draw goes up by about 180% (conservative guestimate because different models use different motors etc) once the motor that spins the disk spins up and the armature motor (or motors in some cases) start going. Initializing the ODD takes very little power by comparison as that is mostly firmware.

Hello wardog,

I have to apologize that I overlooked your Post.

My brother in law lent me his power monitor and I did a measurement with it.
When the PC is idling it draws 20 Watts.
When it tries to read the DVD I can see power draw of 25 Watts.
All to be seen in an LCD display.

But  -  the power monitor has a funktion to show me short power peaks not displayed
on the LCD.
In that mode it shows power peaks of over 70 Watts and I think this happens when the DVD
is read.
Unfortunately the peak display mode does not show any timing, so I don't know when
this happens.
Of course over 70 Watts is too much for the power brick, whatever it does then, don't know.

My next step is to buy a new power brick with at least 90 Watt to see what happens then.

90w should do the trick. If you are not wanting to spend a lot you can check second hand PC stores for old Laptop bricks, many go as high as 110w. Just be sure wherever you buy from has a warranty. I can pick up things like that here with a 6 month warranty, not bad for a second hand store Wink

Nope. Not 90w either. The below is what I read in the Q1900TM-ITX manual(pg8) before asking of what power brick.
