8x dvd-r won't burn at 8x on NEC 2510a



Hi, i have a dvd-r (nec nd-2510a) that is supposed to burn at 8x. It was burning at that speed with nero 7 in the past, but in the last month i had to do a complete system restore. Since then, it has given me a max of 2.4x in the nero options. I’m not a “noob” with computers, but i can’t get this to work right for the life of me and its very irritating. Any suggestions or help would be appreciated.


Welcome to the forum.

2.4x is the default write speed when an 8x burner cannot recognise the Media ID of a DVD blank when inserted.

I’d suggest that you’ve now using a different media than before. Updating your firmware to the latest available from NEC might overcome this. It can be found here .

I’m moving this to the NEC sub-forum of Optical Drives.


Make sure DMA2 mode is enabled.


Penn0116 - Did you ever get your problem fixed? I am basically having the same issue.

I have a Gateway GR-500 with a Double layer 8X DVD+/-RW drive that should according to Gateway

Write speed
DVD-R: 2x, 4x CLV, 8x ZCLV
DVD-RW: 1x, 2x, 4x CLV
DVD-RAM: 2x, 3x ZCLV, 3x-5x PCAV (Ver.2.1)
DVD+R: SL - 2.4x, 4x CLV, 8x, 12x ZCLV
DL - 2.4x CLV
DVD+RW: 2.4x, 4x CLV
CD-R: 4x, 8x, 16x CLV, 24x, 32x, 40x ZCLV
CD-RW: 4x, 8x, 10x, 16x CLV, 24x ZCLV

Originally I was able to burn at 8x. That was about 500 DVD’s ago.
Now I burn at 4x as a max speed.
This problem has been plaquing me for several months.
I am using Nero SmartStart for burning.

At first I thought it was the media but after many different brands I do not think that is the issue.

I even got so frustrated that I did a destructive reformat.
And still the problem exists.

A call into Gateway tells me that it is actually an
NEC ND-2510A, even though my device manager tells me it is something else.

I tried a firmware update from NEC and I received the message “Target NEC ND-2510 is not found correctly”

I am about this close to buying a new burner.
I’m still curious why I am limited to 4x burns.


You cannot crossflash with offical flashers.

Try binflash.


Also is the drive running in UDMA 2 mode?


UDMA 2 mode would be found where?
In the BIOS?
In Nero?
Under Device Manager, Properties?

Thanks. I will check when I get back to the house.


Also you might want to read here:



I don’t know if your problem was like mine, but when i had the same thing as you, I now put a blank disk in before i open nero and start the project, and it gives me all the speed options.
Sorry if this is not your problem!


Surely this person has a disc in the drive :doh: Could be :o


PIO off. DMA 2 on.
New issue … 1st attempt at a burn speed of (8x) showing.
Hurray but wait. What’s that the burn button is grayed out.
Possible corrupt program?

And Penn yes that is just like the problem I am/was experiencing.


Which drive is the target drive?
Is the media inserted really BLANK?


The D Drive is the target.
Data is burned from HD to NEC 2510A.
And yes the media is blank.


And the “D drive” is what drive??
