Hi cynthia, and thank you for your response. It's really interesting! The scannings (quality %) are done in a BenQ DW1640 BSRB at 8x speed with Nero CD-DVD Speed. I know that my Sony DRX-810UL can be crossflashed into BenQ DW1640 and Plextor PX-740 since all three come from the same OEM. So, it may make sense to turn it into DW1640 just to see if it helps. And if it doesn't, I can turn it back into DRX-810UL. Well, now I have something to play with... I only need to find some time to do it...

Hi guys, thank you for your prompt responses. Let me clarify some issues. I'm not against your recommendations. Indeed I appreciate them very much. Thanks! Means just what it states, there was an attempt - or several - made to rewrite the data to that particular area and it didn't work. (And please post a logfile next time.) I'm sorry, English is not my native language, and for me 'Invalid Address For Write' may mean a try to write to an address that, for example, is out of range or something like that. As to the log file, it was almost identical to the one that I referred to, so I just cut and pasted the fragment that I was interested in. Thank you very much! That's really a most impressive source of information about drives and media I'ev ever seen! Actually I was so naive to think that today I can trust at least to well known brands... and it turns out to be not true... I understand that. I was just confused by that message about Invalid Address. May it make sense to change it to something more clear? You are absolutely right! I looked at quality of that disc and it's terrible! It seems that Layer 1 is about to die - average PI for Layer 1 ~600 and average PIF ~3! No. I always burn at 2.4x.

Hi everyone, I'm a newbie in burning DL discs and my very first attempts to burn them failed completely. I needed to burn a 7.84 GB ISO, so I chose to use a DL disc. I was limited in time, so I had to use a TDK DVD+R DL 8X DL disc (ID: RICOHJPN-D01-67). Unfortunately, my DRX-810UL failed to burn 3 of them with same errors as in http://forum.imgburn.com/index.php?showtopic=5876&st=0&p=61654: ... I 22:23:36 Writing Image... (LBA: 0 - 4125759) I 22:23:36 Writing Layer 0... (LBA: 0 - 2062879) I 22:31:01 Writing Layer 1... (LBA: 2062880 - 4125759) W 22:32:42 Failed to Write Sectors 2198368 - 2198399 - Write Error W 22:32:42 Retrying (1 of 20)... W 22:32:42 Retry Failed - Invalid Address For Write ... Every time Write Error happened for different sectors, but always when writing Layer 1. I tried imgBurn v2.3.2.0 & v2.4.0.0. Last time (of 3) I switched from SPTI to ASPI, but with the same error. I know (from reading this forum) that people think that all discs but Verbatim are considered as 'dodgy', sh%$#^, etc. But when I tried to burn those 'dodgy' TDK's in my old NEC ND-3520A, it burnt them just fine. I used imgBurn v2.4.0.0, SPTI mode. And I did it on the same machine with the same set of running software. After that I incline to think that the problem may be caused either by my Sony DRX-810UL or by some incompatibility of the burning software with it. My questions are: 1. What does 'Retry Failed - Invalid Address For Write' message mean (its part about 'Invalid Address') and what causes it? 2. Has anyone happy owner of Sony DRX-810UL managed to successfully burn a DL disc in it? If so, what type? Thank you in advance. I forgot to add that I upgraded Sony DRX-810UL to fw 2.0f and my NEC to 3.07.
