Just a little note:

I've burned a bunch of Primedisc 4x DVD-R whitetops @4x with Nero (with verify) and had no problems.
Then (I didnt noticed that) stupid windooze just forced downsetting DMA > PIO-mode for unknown reason, but Nero already showed 4x burning... but the timecount showed me the truth... 2x speed of course.

The problem is, all these 4x media burnt at 2x had read-errors and verify-errors in the last 200/300mb of the discs. D@mn.

So, I just removed the IDE-channel in Devicemanager and plugNprayed it again back, set again to FORCING DMA-mode (which was already enabled...) and rebooted.
Started again and now burning again at decided speed (4x) and with NO ERRORS.

:evil:

Running XP I guess? It seems that XP does this sometime for some reason

I'm running win2k and no problems at all

No, Herrie, thats not the case, and thats why I find it curious.

I am currently using Windows 2003 (Server Enterprise) and had even with W2k (SP3) never such problems!!

Officially there isn't no 1x media, because the media code can only be 50 or 52. 50 = 2x, 52 = 4x!

No "officially" there are no 2x media, only 1x and 4x DVD-R speed are approved by DVD forum.

NEC however seems to not have implemented 1x speed on the ND-1300A and this will give you problems with all the cheap crap 1x DVD-R media which are of to bad quality for 2x burning. This is probably why NEC didn't bother implement these media in the firmware too and even if you can burn to them now with the hacked firmware the writing quality will be horrible on most of them.

Ok, there´s been some lines about Datawrite redtops but not a real confirmation if they work or not. Ppl claim they can burn them either witn 2x or 4x.

But is the verification really 100% allright afterwards?

You can use Nero CD Speed with the Scandisk option too if you have doubts about the verifying process.
Best is to use another DVD-ROM to proceed with the media to be sure.

Ok.

Is it possible to make the NEC write these 1x media @ 1x speed?

Does anyone know some cheap media here in Stockholm that works?

I didn't really check it with my NEC lately, but I recall my NEC has problems reading back the Princo's written @ 4x. But when I read it with my Pioneer 305S I don't get any errors!

So maybe it's some problem in the reading part of the NEC?

I will do some testing with reading back the Princo's in my NEC tonight

@ Herrie

Really NICE work, you've done so far.

Just some dumb question, is there a list, which states all supported media by your hack? :oops:

Especially I would like to know, if the Princo and DataTrack 2.0 (should be Princo) 2x/4x are supported by your hack.

Second I bought a DVD-R by OKANO (no manufacturer ID), any chance to support these kind of medias? 8)

Keep on your good work.

Do Datatrack have a Princo media code also? Princo 4x seems to exist with 3 different media codes. Some of them seem to work without problem @4x, others only @ 2x.

All discs have a media code, sometimes it might be a blank one! Could you please post the media code of those OKANO discs, so I can check if I think it's supported. I suppose it is, but I like to verify

[edit]
I cannot provide a list of all supported discs, but I CAN provide a list with all supported media codes

Herrie,
as a 1100 owner I wonder whether all the newly supported media are -R(W)? Or did you enhance the list of +R(W) too?
I'm just wondering whether you media list might be better than the +R(W) media supported by the 1100A and hence worth cross flashing to avail of the enhancement?

I didn't find a table for the writing speeds and enabled/disabled switch for +R(W)

There are only 19 +R media codes and 13 +RW media codes in the f/w of the 1300A. I didn't take a look at the 1100 f/w yet, but do you have any +R(W) that is currently not working? Could you also provide the media code (from dvdinfo) so I can see what I can do

Herrie you really rock !

I'm now able to write all my white printed top Princo 4X @4X

Thanks a lot for all you done !

My understanding is that +R discs do not have a defined writing speed - they will all work as fast as the drive you put them in is capable of.

No, thats not true.
There is more likely extra codes on every DVD+R/RW media that tells the drive how fast/at which speed the media can be written to.

You cannot write a 2.4x DVD+R at 4x and you cannot write a 2.4x DVD+RW at 4x speed!

Hello,

I've burned some White Top PRINCO DVD-R 4X @4X and there were no problem during Burning / Checking.
I tried the burned dvd on my two dvd player:
- ACTIMA 10X
- QSI Combo DVD/CD-RW
No problem for reading them.
I also made a CRC Check on the content of the DVD and it is identical to the CRC Check of my original files.

So for me there are no problems with White Top Princo 4X DVD-R

Thanks a lot for your work Herrie !

so thanks a lot , hope all of the users from this forum will report all the new supported medias

Interesting - and yet they do not carry any speed markings on their packaging (at least, not on the ones I've seen). I'm bsure you're right, it just seems that the classifications are not displayed, except on the +RW discs.

chef · **Posted:** Mon Jun 16, 2003 2:43 pm

Hm, maybe.

My 4x DVD+R shows "4x certified" on the package.
Unless it is not extra marked I think all other media is just for 2.4x DVD+R burning (produced).
The same for DVD+Rw media (at least for my medias which are printed/marked at all...) .

As only Verbatim has 4x DVD+R media on the market at the moment, it's difficult to tell if there's some kind of identifier. What I did not is that there's one obvious difference between the media codes

08 02 00 00 A1 0F 02 00 00 03 00 00 00 25 F2 9F .............%..
00 00 00 00 00 00 01 4D 43 43 00 00 00 00 00 30 .......MCC.....0
30 32 00 38 23 54 37 13 02 4A 71 02 90 66 16 16 02.8#T7..Jq..f..
0B 0B 0A 0A 01 1C 1E 0B 0C 12 12 01 00 00 00 00 ................

All 2,4x media show 00 at this place

So I guess that determines the speed! But for now I'm not able to tell!

here goes the sentinel dvd-r 2x code as requested by Herrie :

00 42 00 00 01 40 C1 FD 9E D8 50 00 02 7A 0C 15 .B...@....P..z..
77 78 90 00 03 00 00 00 00 00 00 00 04 00 00 00 wx..............

I don't really understand anything when i read this but if you can

that's cool !

Ah it's the one with the media code " " 6 times a space

And it should burn at 2x like it does. I like to know the media codes, because in this way I can verify if the media that have the status "experimental" are working correctly

Yes, it is a Verbatim 4x DVD+R.
Thanks much for the explanation, Herrie.
We all have to thank you - profiting from your hard work & knowledge!!

Lots of new media support for NEC ND-1300A after F/W hack!
