An extra big thanks to Liggy for his new bitsetting 3.04 firmware
This firmware is only compatible with NEC ND-3520 and IO-DATA rebadge
DO NOT try and FLASH a ND-3500 or rebadges drive with this firmware.

Hopefully improved the burn quality on the following media

LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on Liggy’s 3.04 Bitsetting firmware with version and name string changed to ND-3520A 1.UF, with riplock removed and RPC1

Q: How do i flash my drive with this firmware?
A: The firmware is now bundled with Liggys Binflash Unzip then run the package, now click on the FLASH button. The firmware will now be uploaded onto your drive, when completed you will be prompted to restart your PC.

To Flash a drive in DOS, LINUX or MAC. Use a current version of Binflash. Run Binflash with the commands necessary to load the firmware package. Binflash will accept either a .BIN or a .EXE file and flash your drive.

Q: What are the risks of flashing my drive with this firmware?
A: Great care has been taken to make sure your drive is not damaged in any way by using this firmware. However, you flash your drive with this firmware at your own risk. Neither I, Liggy, or cdfreaks will be held responsible if your drive or media is damaged in any way.

Q: Will flashing my drive with this firmware void my guarantee?
A: Yes, flashing your drive with any unofficial firmware will null your guarantee. If something should go wrong with your drive, you should buy a new one and not RMA the drive.

Q: Do I need special IDE drivers when running this firmware on my drive?
A Like all optical drives. It has been proven they work best when using Microsoft’s default IDE drivers. This is a must for this firmware.

Q: Why do i not get good results when i burn media on the modified media list at MAX speed?
A: This is largely down to the quality of your media. If the speedups don’t give you good results. Set the burn speed lower. This firmware will give good results at the stated stock firmware speed, without having to flash back to a stock firmware.

Q: What about media not on the modified media list?
A: All media both SL and DL not listed in the modified media table use the default NEC STOCK write strategies and speeds. If you don’t get the results you expect with media not in the modified list, this is a limitation of the media or drive, not this firmware.

Q: How do i set SL bitsetting for +R media?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DL +R bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DVD+RW bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Also submit a (data transfer test) Using the ND-3520 or ND-3500AG, again saving the screenshot from CD-DVD Speed

Disc Quality scans can be submitted with NEC Drives using CD-Speed with scan speed set at 5X or 8X
Note Version 3.75 or higher is required for PI/PIF scanning on the NEC drives.

Below is some additional info from the author of CD-Speed.

(Liteon drives) using K-Probe @4X scan speed or CD-DVD Speed (disc quality) @4X scan speed.

If scanning with a Benq drive. use CD-DVD Speed (disc Quality) @8X scan speed.

Thx again Dee
Might be an idea to start a new thread for the scans, or do we post them here?:slight_smile: :bow:


We’ve always posted them in the running thread (here) its worked good so far. :slight_smile:


THANX DEE :slight_smile:



Way to jump right on it Dee !

I’ll just flash back and fouth till you add the + SL bitsetting. All my current blanks are + TY and Verbatium MCC 003 at this time, and the DVD-ROM is needed for compatability with a few players.
Thanks for all of you work and efforts on the NEC.


Disc Quality scans can be submitted with NEC Drives using CD-Speed with scan speed set at 5X or 8X.

Which one to start 5 or 8x or rather which would everyone prefer??


Which ever speed you like, for now i’ll be submitting scans at both 5X and 8X. i guess we will wait and see how it goes.

5X scan takes 16 minutes
8X takes 10 minutes


MCC003 (verbatim)
Burn speed 8X
Firmware 1.UB

First scan at 8X
Second scan at 5X


At last 6x support for RITEKW06 - Traxdata branded!
Quality scan at 8x eec with 8x and 5x scan speeds.
Comparison with the Liteon for the scan Here
Not too sure about the 8x scan speed as yet - but we are still learning :iagree:


Thanks for the fast new version firmware, :bow: I really would like that you put in all the new firmware as you made before, always the possibility to do bitsettins :iagree:


We are working on this :wink:


5X is much better :iagree:


Ooooh, this is just GREAT.

Thanks Dee and Liggy :bow: :bow: :bow:

I hope we will see 3500 firmware with PIE/PIF functionality sooon. :bigsmile:


These two scans are of the same disc recorded on the NEC 3520 with 1.UB
first is canned on the 3520 and the second is on the BenQ 1620. Seems odd how stepped the Benq1620 scan is and the 3520 scan is flat. Both show about the same quality scan but get the results way differently. Other discs recorded on my pioneer and older NEC1100A don’t show the stepped quality scan on the Benq 1620. Just got to wonder why.

Good overall quality improvement on the Ritek discs with the new firmware.


BenQ 1620 is more jitter sensitive then other drives when reporting PIE/PIF from what I’ve experienced.
I also use KProbe to verify my qtests. This speed steps you talk about are also clearly seen in KProbe…

But finally, it’s up to you to trust and rely on which ever you want… :smiley:


Nec 3520AW FW 1.UB
YUDEN000 T02 DVD+R 8x
Burned @ 12x
Doesn,t look like much of a difference in scan speeds, but so far 2x98 Quality scores and 5x97 qs so far looks promising. :slight_smile:


Can you add a scan with the lite-on drive to compare burn quality with earlier firmwares ?

Thx 4 the new firmware :smiley:


Well this had made my Day! I got a 99 QS with my BenQ today so this makes 2! My computer will probably blow up tomorrow. :slight_smile:
@ Hurky, attaching a Lite On scan for you.


Not to sound like a complete retard but what is PI/PIF Scanning?


wow dont ever buy office depot branded G04’s

this made me so sick i had to cancel it

was burned a week ago… same burner… at 2x
