PioData DVS-S21DBK

There is no possibility of overburning on DVD + R, DVD-R, DVD-R DL.

I will check these BenQ CD-R Mini tests

Yeah, great review!

Sadly all overburning capable drives are vanishing.

It vanished long time ago, hm?

My only dives which could do that were made til 2006 or something, Plextor 755/760 and original Benqs. But both could only overburn DVD+R, IIRC

Never had a drive which could overburn -R, but IIRC some Pioneer and Pioneer-clones could do it.

However, some newer drives like Pioneer DVR-S21 (QSI) and Pioneer BD-drives don´t read data beyond 4482MB

Tried to get a Piodata at Amazon, but after a week the available 5 drives vanished

IIRC, Nu-tech drives could overburn DVD-R too.

In comparison “many” drives could overburn DVD+R & DL, of course the famous real Plextors and some BenQs.

Huh, in general? Didn´t I read somewhere the Piodata and Optiarc 5290S can only overburn specific DL (MKM 003)?

And the next question: Can other/actual drives read those media?

They should, but overburning media is always a risk and not necessary anymore since years (to overcome copr or similar).

BTW, also those famous Nu-Tech dvd burners had a BenQ design. :wink:

Overburning DVD was more an experiment and because DL are much more expensive. Verbatim DL-media costs over 4x the price of SL

NuTech was rare here, even I had none. But it´s interesting it overburns -R, especially if it was a Benq-design. Benq always push +R and maybe it was the only brand which had a 16x DVD-writer which only support +R

BTW, the correct name of the Piodata is DVR-S21, not DVS or DVD :wink:

I saw the new firmware available at Piodata’s website.

Yep, Vinpower-Support gave me the link. I made two burns with it

But problem with MCC 004 is still active, at least if scanning with a LiteOn

The updater is picky, I tried 3 different SATA-chipsets to get it work

You mean Sata to USB chipset?

Did you report the problem to Vinpower?

Yep, they give me the new FW and I should try it. I will send them The latest results

Nope, because my PCs with bunches of ODDs need more than the onboard-SATA have PCIe-cards which offer also SATA, chipsets from Marvell, JMB, AsMedia, Silicon Image, LSi

If they are using firmware from LiteOn and manage to solve the problem, then there is a chance that it will also be resolved for LiteOn drives too.

Does vinpower write their own firmware versions, completely independent of LiteOn ?

The question is whether Vinpower provides their fw patches back to LiteOn. If they do, then another question is whether LiteOn actually uses any of these vinpower fw patches.

Vinpower offers newer FW than LiteOn, so I guess they really dow something by their own. But I doubt LiteOn will get these FW

Features of Vinpower-only FW:

4x-writing with some DVD-media
8x CD-R-writing with some media
Overburning of DVD+R DL

At this point I wouldn’t be surprised if LiteOn has already tried to sell their dvdr drive division to one of their large clients, such as HP, Lenovo, or even Vinpower.

HP and Lenovo would probably have extensive experience with running large manufacturing and intellectual property divisons (ie. patent payments, etc …).

Though I don’t know if Vinpower would have the deep pockets and/or extensive experience in running their own large manufacturing operations.

Dunno how big Vinpower is, if they can handle this. I have seen Vinpower also uses LG-BD-R-drives and some disc-duplicators with Pioneer BD-R-drives

New firmware from Piodata that fix the MCC 004 burn quality issue.
