NEC 3520A - Failure burnins DVD+R DL disks

[kohno97]

First of all, hello everybody!!!

I have a problem with a NEC 3520 drive, which fails systematically to burn any DL DVD disk, although it has recorded perfectly any DVD+/-R single layer and CD-R disk.

I have tried different disk brands and recording speeds, but no success.

I have also flashed its firmware to the latest (3.04) version of its "official" firmware, but no luck.

I have tried the recorder on two different systems, both of which managed to record prefectly DL disks when I replaced the NEC with an LG 4163 drive.

No Intel software on any of the two machines.

I have attached the Nero log for the latest failed burn (Used software: DVDDecrypter and Nero 6.6), should it provide any hints. The burn failed as soon as it started "Writing layer 1", but then nero started "Writing DVD high compatibility borders". The resulting disk seems to be writable, but when I select "Resume multisession disk", Nero does not allow me to select the existing 480KB session 1.

Any ideas? Is it defective drive or can I do something different?

Thank you in advance...

What media manufacturer do you use ?

[kohno97]

I've used several, like TDK, Verbatim, Ritek and EMTEC.

I've forgotten to say, the drive is installed as Secondary Master.

reading the txt file I see several scsi errors...maybe U should try aspi for all(4.60) and see if it makes any difference...just my 5 cents

[kohno97]

ASPI 4.60 installed already...

Why don't you try dvd decrypter to burn the disc? (only to burn, not to rip... :bigsmile: )

What is the media code from TDK and Emtec? (use dvd identyfier to find out)

[kohno97]

I' afraid I don't have any more disks available right now to do any more tests... if I am to spend about 60€ for DVD DL disk coasters, I can buy just another LG recorder and do my job!

As for the Emtec disk, it is a "RITEK D01" for the TDK I don't know (the recorder is of a friend of mine and he didn't keep the coasters)

So, what is all the noise about DL burning?

[kohno97]

What do you mean?

[nautilus7]

Greek version: Εννοώ ότι αν δεν σκοπεύεις να γράψεις άλλα DL δισκάκια, γιατί άνοιξες το thread αυτό; Εκτός και αν νομίζεις ότι θα βρεις τη λύση στο πρόβλημά σου χωρίς να πειραματιστείς.

English version: If you wont burn other DL DVDs why bothering?

[kohno97]

I will if I have something new to try... but I suppose you are patrly right. I am of course willing to attempt to write more disks, but I need an idea to try something different - repeating the exact same steps does not lead to solutions. Sorry for the misanderstanding.
