LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on MD16 firmware 1.F3 with version and name string changed to ND-3520A 1.U9, with Bitsetting 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: 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.

Still waiting for a confirmation these MBI 01RG20 can really be burned at 8x :confused:
My Memorex MBI 01RG20 are horrible even at 4x.
I only have some few left but i´d like to beware others to kill their media.
Otherwise, thank you for working on and improving things!!

Thnx Dee for the update

Thanks Dee.

How about making +RW media burn from 4x to 8x/12x/16x ?

hehe, I bought my 3520 today, nice to see a new flash the same day. I am gonna check it out now.

:bigsmile: :bigsmile: :bigsmile: :bigsmile: :bigsmile: :bigsmile:
Thank You Dee

Thank you!! :bow: :bow:

Dee did u change the write stategies for the Infome R20?
Or is it just a bad/strange disk?

I’d bet it was a bad disc LeXuZ.I get those kinda results with RITEKG05 stuff all the time.It’s just the drive slowing down to make the quality of the burn acceptable,which means that there’s a flaw in the disc(quality).

Thanx for the info Nosmartz

Nice. You guys are awesome. One question though. I’ve been doing some testing with 1.U6, and now 1.U7, with Riplock removed. Even with this riplock-removed firmware, my ripping speeds (using a typical, store-bought movie DVD) are IDENTICAL to the original 1.04 firmware. Somewhere between 2X and 4X. Can you confirm that the riplock removal is correctly implemented in this firmware? I mean, as far as I can tell, the riplock removal in this firmware has absolutely no effect on ripping speed. Maybe that’s normal with this NEC 3520A drive, but I just thought I’d ask.


I haven’t seen anyone yet do a disc at over 8x(DL) with the 3520.I could be wrong but I haven’t seen it.That’s why I use a dvd rom(10x) :slight_smile:

Thanx Dee,You absolutely rawk.The MAXELL’s are back.I owe you for these.I’m quite happy needless to say.

Maxell 002(just a tiny dip at the end but that should be OK).
burn’t at 8x

Maxell RG02
burn’t at 8x

Not that this really matters, but one of the installer packages has a typo. It’s name is LD 3250 instead of 3520.

Again, don’t mean to nit-pick, but I figured the authors would eventually want to fix. :slight_smile:


good catch. :slight_smile:

Dee, what’s the status of the Verbatim 16x MCC 004 write strategy? Will it change in light of the results some people were having in beta 6? You mentioned here that you might go back to the beta 4 strat.

Well spotted :slight_smile: Sorted now
me bad :o :stuck_out_tongue:

After double checking MCC004. It was left as it was.

Hey guys! thanks for the new firmware lol! bought a 3520 yesterday and flashed it twice already! but still a question…do you ppl have the possibility to take a look at That’s Write DVD-R 4.7Gb 8x dics? I’ve got like 100s of them but i can only burn them at 4x :frowning:
