I'm testing a sony dru 700A.
Take a look at those reading tests:

It seams write quality is very very bad!!
May be this is a defective drive?

Andrea

i tried 2 different 700A's. and i created alot of coasters with both :-(
memorex, sony, and tdk media

Perhaps you could try using the LiteOn VS04 firmware, as the VY02 firmware for the 700A is somewhat buggy.

I just tried the last LiteOn VS04 firmware but i continue having problems: i has not tested many media but i can say it has problems with verbatim, memorex, fortis, ritek!
Really a very bad dvd burner!

Andrea

There is a new Firmware from Sony Japan :

thanks for the link. I'm testing new firmware

is it possible you could extract the .bin from your drive? so we can have a play around with the new firmware

I just send it to code65536
Andrea

excellent

Thanks.

RITEKG05 is still very broken with this new firmware.

At least MCC003 now burns OK at 8X
RITEKR03 burns OK at 8X
MCC02RG20 burns OK at 8X
RICOHJPNR02 burns OK at 8X
TYG02 burns OK at 8X

Well, that's because, despite its timestamp, VY05 is actually somewhere between VS01 and VS03 in age. See my post in the VY05 thread in the LiteOn forum (speaking of which, can someone with privs in this forum move this thread?)

I tried VS04 firmware on my sony dru 700A and i still created coasters with sony, and memorex media then I wrote with sony dru-510 from sme spindles and they play fine
i'm trying the nc 2510, so far 3 on teon media no bad blocks on nero scan and they play on my set top :-)

Well RITEKG05 is still broken on VS04 too, perhaps Liteon need to know this.

*wonders how it does with US0N since that is the newest firmware available right now, newer than even VS04*

Though, with my current strong dislike of Ritek and their crap, I'm finding it very amusing that a fellow Taiwanese company isn't properly supporting their media. But I guess Ritek users won't see the humor in that.

RITEKG05 perform perfectly well on other quality DVD burners, notably Pioneer and NEC2500 (Herrie), and they nearly perform well on the Liteon drives. The problem only occurs when doing an 8X burn, the writing at 4X speed must be using a wrong strategy, as PI errors approach 700, PO errors approach 150, yet in the 6X and 8X burn areas, the PI and PO counts are quite low.

The problem not only occurs on DRU-700A, and 832S drives, it also occurs on 812S drives, even with firmware US0N.

I have emailed Liteon about this, I'll let you know what happens.

*nods* I agree that it's a problem with the firmware's write strat, since it does perform well with other drives. I was just commenting on the irony of it from my anti-Ritek standpoint.

Anyway, if US0N doesn't do well with this, then VS05 won't, either, because, as I understand, the two are very similar. Perhaps in a firmware later than either of those. *crosses fingers*

I can confirm US0N also doesn't like G05

I am kind of confused... are you guys more mad that the 2x certified media doesn't burn at 8x? or that the DRU-700A gives high PI values when you try to burn at 8x with 2x media?

I have no problems burning 4X media at 4x or 2x media at 2x with my DRU-700A with any firmware. You make it sound like the DRU-700A and SOHW-832 don't work, period. Reading the thread titles alone is enough to make someone consider returning their drive.

I'll use my car analogy again. If you purchase a car that is intended to go 50mph, you have no legitimate complaint when the car is unstable and uncontrollable at 100 or 200mph. It's like someone complaining that their Porshce doesn't perform the same when they decide to use regular unleaded instead of premium.

Not only Ritek burning bad with Sony 700A..... Also Prodisk, Optodisk, and even MCC =) I have two drives now - DRU 700A and NEC-2500. No problems with NEC. Now I'll wait new firmware for Sony, or change it back to Liteon 812S

The most problems are always at the beginning of disk

Must be a really rubbish drive because it should work with the Ritek, they are the best discs by miles. Has anyone had experience using the Fortis discs, good or bad?
