RITEK R02 DVD+R problems


I’ve just bought a Sony DRU-810A and crossflashed it to a BenQ DW1640 with BSLB firmware. It was the easiest, and funnily enough cheapest way for me to get a DW1640. Upgraded from a NEC 3500AG, btw.

Today I decided to clean out my HDD and burn some less important data to my last batch of RITEK R02 discs. They are rated at 4x speed and were sold as Datasafe 4.7GB General Purpose DVD+R Ritek Printable (www.datasafe-media.com). Media details from CD-DVD Speed are included below.

My problem is that each of the four discs I’ve written so far show PO failures for the last 5 or so sectors of the discs. I’m using Nero ( seems unfinished somehow). The BenQ has WOPC, SolidBurn and Overspeed enabled using QSuite 2.1. The funny thing is, that this problem shows whether I’m using 4x speed or overspeeding at 8x speed. Up until the last few sectors the discs show a consistent quality of 97%, which I’d call pretty good. All other values are very good too.

Does anyone have a clue what may be wrong here? Like I said, burning at 4x or 8x makes no difference whatsoever quality- or problemwise. The discs also do not contain the same amount of data, although they all contain slightly more than 4400MB, but stay below the 4482MB limit.

Looking forward to some input!

Regards and TIA,

I hope you don’t believe in this.
Get some decent media for a few oere (cent) more and you will be able to burn a full disc.

BTW, RiTEK R02 is not supported in BSLB anymore. Check you have learning for unknown media ticket in QSuite then burn some more at 4x max with SolidBurn on. Avoid burning past 4GB.

While it may very well be the fault of the ritek discs. That problem usually happens if you don’t eject and reinsert the disc before scanning it.

Thanks for the quick reply! I’m well aware that these discs aren’t grade A stuff. That’s why I’m using it for less important stuff (stuff that might be handy to have, but not essential). I’ve some TY02 for the good stuff. The reason I asked is that I’ve never had problems with the Ritek discs in my NEC 3500AG before, although the NEC only burned them at 4x speed. Funny really that the DW1640 burns them in excellent quality …up to a point, that is.


At what speed are you scanning?
8x is recommended.

off topic

Keep NEC 3500 in your box if you can. One of the best burners ever and still NEC’s best burner for low quality/speed media (with Liggy/dee-27 firmwares). :slight_smile:

I’m scanning at max (both for the Disc Quality and Scan Disc feature). I just burned one of my TY02 discs to compare with the Ritek discs, and it seems to exhibit the same problem.

The NEC was sold off btw… I’m already regretting that! :frowning:


Problem solved!!!

Must admit I was a bit peeved to see my Taiyo Yuden T02 media fail too. Then I found this other thread about the “No additional sense information!” error.

I usually disable tray cycling since I consider it needlessly straining the tray mechanism. Well, I’ve now rechecked some of my media and none of it exhibits a problem. Neither the Yuden nor the Riteks. Quality scores of 97+. Consider me relieved and pleased! Especially since I can overspeed those Ritek discs to 8x speed… :slight_smile:
