1.07 v2 Dual Layer Bitsetting Beta 5

Yes...
But, now I have the proof it is the firmware...

I just downgraded with the official firmware 1.07, and now, it works perfectly...
When I flash with your 1.07v2 beta 5 that doesn't work any more...in Nero at least ! And with the previous version of your firmware, that doesn't work either.
Another thing that I've just seen : whith the official firmware, the led of my USB2 enclosure goes red during burning and access to the device, but with your firmware, the led stays green, maybe there's a link ? If you've got an idea I'm OK to test...but for the moment I've to keep the Nec 1.07 official firmware ! :'(

@Rebel2K
I had a problem like yours. Nero just stopped at approx. 70%. I had made 2-3 DVD's before and i made 2-3 DVD after whithout problems. But a Kprobe scan turned out worse so now im on 107v2b4 again.
Im fairly new to kprobe but i guess that this scan i ok

In fact, what annoy me the most is the buffer underrun protection which is not active with the Herrie firmware...I don't understand why ! Moreover, apparently that works for Herrie, so maybe the problem only affect the drive when it is connected with USB ?

I have Herrie firmware and buffer under works perfectly on my drive. I am
use dvd decrypter for burning. I really doubt firmware is the issue here. My
drive is internal.

is the usb the problem?

i use the nec internal and no buffer probs.

Erh, so it seems to be a problem linked with the USB connectivity...Because, it is sure that something change when I flash with Herrie firmware...Maybe it is due to the fact that Herrie firmware is based on the HP one...? What is your advice Herrie ?

Well, sorry to say it, but I have some Buffer Underrun issues with beta5 too.

Sek. Master Nec 2500
Sek. Slave Toshiba SD-M1612
Nero 6.3.1.6

Normally I have no problems at all making a straight DVD-copy at speed 4x. Used read buffer 100% and Buffer level 90-100%. With beta5 Used read buffer fairly quickly decreased to 50% (and stayed there), and Buffer level now and then fell to 0% a couple of seconds and then went up again. In the last 10% of the writing (used all 4.37GB) the NEC occasionally paused for some seconds (no light), wrote for some seconds, pausing again and so on. Took a little more than 17 min for a burn.

Flashed with beta4. Made the same burn and all was back to normal! I'm sticking with beta4 for now. It's a good one, Herrie :-)

Burnt a DVD with the leaddat01 DVD -R 4x(Great Quality Brand) From Fry's electronics.. Burned at 8X + without problems tried it on both dvd's reads plays fine and quality is great...

Using a Pacific Digital 8X+8X-(nec 2500a)

Still have a question on the rip unlock is that part of this firmware version and if not can you use 2 types of firmware at once? The current herrie and then a riplock one?

What do you think about this??
Is it a bad result??


DVD-r
ID: MBI01rg20

I think it's a good result

Mine has got the riplock removed too! And NO you cannot use two versions of a firmware at the same time!

And for the buffer problem ?

Haven't got a clue It might be a small bug in the HP 520 firmware. I received a newer 2510 firmware with normal version numbering (instead of K0P2), maybe I'll release a version of that one too, so you can test The only bad thing: it doesn't support bitsetting

Arf, for bitsetting, that doesn't mind...for the rest, I'm ok to test, e-mail me the file when everything will be finished !

I just tried a burn with NERO and beta 5 and got the error underrun problem as well. I dont think it has anything to do with USB.

Maybe it is a small bug yes...as Herrie said !

apologies! - wrong post placement

ive seen external usbs have issues with just stopping as you say when burning. it has a problem with the usb2 architecture and certain firmwares my external usb2 maddog drive used to do it all the time with the hp firmware. i know more programs than nero have this issue as decryptor has it too but at least decryptor tells you the real problem..a semaphore timeout has occured. im not sure if its been researched by hp or not but ive also seen it with my external nu drive too so its not just herries fw or hps ive seen it alot. id say its more a windows bug with certain firmwares, if you want to see more info on it go here although he thinks its the external usb2 chipset and i think its a combination of the chipset and certain firmwares. it could be bitsetting firmwares and the usb2 chipset what im thinking.

it looks like the only way to fix the above issue is to get a better usb2 enclosure..like i said the maddog ones use the ali bugged chipset.

Ok, but the problem for me is not to know why the buffer empties itself, but why when it goes down to zero the burner can't start again as it should normally do when the buffer is full again !

dma on if it's internal, xp sp1 or usb2.0 drivers installed? there may be a bug but to be sure you have to verify all these things. you could try a different burning software also.

I already have tried all of that !
I've changed of software, Nero and RecordNow react with the same error, XP SP1 and USB2 drivers are ok, internal has not been tested.
But, with the official firmware without changing anything the buffer underrun protection function like a charm, so it's sure that comes from the Herrie firmware !

Try pulling your drive from the external case and install it into your PC. Then burn a disc using Herrie's firmware and see what happens. That would certainly help prove your case.

so this firmware allows for dual layer burns? so does that mean i can do a direct copy of a DVD9? if so, how would i go about doing this?

honestly, my main motivation of doing a direct DVD9 copy is a power saving issue. i don't want to have to hassle with the steps of ripping the dvd, transcoding it, then burning it. i'd like to do a straight copy and have the computer shutdown after it is finished (obviously at night when i got to bed).

thanks.

this is a topic for another thread, bur basically you will still need to rip the DVD, or use a driver like "AnyDVD" to decrypt the disc for copying.

I have also noticed a problem when making my last burn to G04 at 8x. The burn was a good one although the NEC could not read it. However from about halfway through the burn the led started flashing on and off.
To prevent any damage to my drive I have reverted back to b4. The led does not flash with b4 even when trying to burn at 8x.

With b4 I have tried out two bulkpaq +r disks with bitsetting enabled.
Perfect burns at 8x. Read by Nec and by Toshiba dvd rom with excellant results.
The media code is as follows:-
Bulkpaq +R Generation 4
00000000 08 02 00 00 01 0F 02 00 00 03 00 00 00 25 D6 5F .............%._
00000010 00 00 00 00 00 00 01 49 53 30 31 00 00 00 00 30 .......IS01....0
00000020 30 31 00 38 23 54 37 13 02 4A 71 02 90 66 16 16 01.8#T7..Jq..f..
00000030 0B 0B 0A 0A 01 1C 1E 0B 0C 12 12 01 00 00 00 00 ................

On the subject of G04 I have just opened another pack and find that the coding is different. I have not yet tried a burn with this at 8x but at 4x the results are very good.

I will let you know if I have any further luck but intend to stay for a while with b4 until this led problem is resolved.
