Hello folks!

First of all let me say that I bought a BenQ DW1620 OEM [had nothing but mediocre (at best) burns with it]. So, I finally gave up and am trying a BTC DRW1016IM [IO Magic rebadge].

Anyhow, I few questions...

I gather that CD Speed and DVD Info Pro do not support jitter and PO failure reading on the BTC drive? Is there any way to change this or is this just something we have to wait for in the future? I'm using firmware A07R.

It seems to burn GREAT [on CMC Mag AE 01 (yes I know this is cheap crappy media - I didn't when I bought it)]. I haven't tried any other media (YET!) I have Memorex [Prodisc S03 -R], Sony D11, TY T02, and Maxell 002. I'll try at least one of each, soon!

A quick question about the CMC Mags. Do some brands not like to be written to the very end of the disc? I seem to get as many [approx] errors in the last few hundred MB of the disc as I do over the entire disc. For instance if I only scan up to 4175 MB [out of 4465], I get VERY excellent results. I can post screen caps if anyone is interested. Is this just true of this particular media or ALL media in this particular drive or will I just have to figure it out on a media by media basis?

Thanks for all your help,
Chad

Can someone tell me why the quality score is so low? This looks like a -great- burn from what I've read about PI, PIF scans etc. And yet its a qual of 77?

Is there one particular thing that lowered the score or is it just a combination of things? I saw much worse scans on the BenQ that still scored in the 90's.

Thanks in advance,
Chad

I just bought on of those I/O Magic from Staples which they are on sale this week. I have a NEC-3500AG for the last few months which I am very satisfied with. When I open the package of I/O Magic this afternoon I found out the drive is BTC DRW10161M, I/O Magic repackages two drives one from BTC and one from BenQ, the BenQ one has D/L writing 2.4X and BTC is 4X. I haven't installed this drive (BTC) since I don't have any experience with and I ma trying to take it back and hopefully exchange it with the package which is BenQ inside. I hope those who do have any experience with BTC drive make comment about whether worthwhile to keep this drive or not thanks.

This is a very good burn I would ignore the score, it dropped down because of the 3 spikes that are above 4. I wouldn't to count to much on the quality score if you see such a good overall scan.

If I could get the BenQ, I would go for it. It has a very good overall permance and it's also upgradeable to 4x DL via firmware.

No

This is a media/firmware issue, you can get this because of a crabby media but you can get this effect also on high quality medias when the writestrategy is not to 100% good.

I just posted these results in another subforum here:

Just starting to understanding DVD burning...this site is helping a lot!

I have a 16x BTC burner (the rebadged I/O Magic) and using CMC -R media burning in Nero 6.6.0.1. Checks are being performed using CD-DVD Speed 3.40. When I use the Disc Quality Test, I'm receiving scores of 95%. Also Scandisc is finding 0 errors.

These are typical readings of my burns at 4x testing speed:
The PIE rate averages around 7% with maximums of around 16-20 with an average of 60,000 reads.
The PIF rate is typically .02 average with a max of 2 and an average of 300 reads.
My burner doesn't read POF or Jitter.

Aren't these results actually good? If so, why with an inferior burner and media?
How much am I missing without POF or Jitter readings?

Thanks for the help everyone!

BTC drive don't support Jitter reading in CD/DVD speed quality test. But, I think it ok for me, I don't care the jitter measure function.

After day and half waiting for any realistic fact on BTC 10161M (I/O Magic repackage) drive and reading about other I/O Magic repackage drive (BenQ 1620) with so many negative comments and complaint about BenQ I decided to install the BTC and give it a try. I ripped a D/L Video with DVD Shrink at speed of 4X and wrote the same ripped DVD with 8X did the testing and every was good and promising then played it in my stand alone DVD player and there too worked perfect. This is so far my own experience with this (BTC)drive.

BTW: I used Maxell 8X DVD+R made in Japan for this coping.

Edit: I have made additional copy of DVD Video with Teon brand of 8X which is not that good of brand name, the burning went perfect and tested smooth and trouble free. Also made two data discs with CD-R none brand name which both came out owesome and great.

BTW: I am using drive stock f/w A07M which came with the drive.

In my limited experience with DVD writers [compared to many others on this forum]. I played with the BTC drive a bit - it seemed to make [again in my limited knowledge of interepretting PI/PO scans] great looking burns.

Its only drawback [but then again my BenQ seems to have the same problem] is writing near the outter edge. If you scan the media up to about 200 or so MB from the end, there are very few errors. And then if you scan that last 200 MB [approximately - this amount varies from media to media] separately there are a considerable amount of errors here. Just to reiterate - this is a problem with both the BenQ AND the BTC. I burned on my BTC with A07R.

From what I've read CMC mag [Teon] will appear to make great burns and great scans on those burns. However, apparently you didn't always get what you are seeing. I can't think of a good example to compare this to, but it sounds like Teon [and most other CMC mag media] are something to steer clear of no matter HOW cheap is. The old "you get what you pay for" applies really well here. hehe!

Earlier this evening I burned a Fuji MiJ [actual MID Taiyo Yuden T02] on my BenQ. It was an awesome burn. I'd recommend this media if you can find it. I haven't tried burning one of these on the BTC however. Best Buy has been having them on sale every other week or so [but make SURE you get the MiJ].

So the short answer to your question... Other than the fact that the BTC can't read the jitter or PO failures [easily detected by trying to copy the info back to your HD from the burned disc - if it won't copy back - you probably have PO failures], I think the BTC [again with A70R in my case] seemed to make some pretty impressive looking burns with very few errors. [Errors meaning PI errors and/or PIF failures - NOT errors meaning info that you can't read back from the DVD].

I hope this helps you out,
Chad

I upgraded the drive F/W last night to A70R and burned two more disk (Teon & Maxell ) both at thier rated speed 8X both came out error free and played without problem. Two problem I have noticed so far: 1) the drive is very slow reader (riping), only read S/L at Max 7X and D/L at 3.8X. 2) the drive does not write the good brand name 8X disk (Maxell, Fuji, Sony ) all made in Japan at the highier rated like 12X or even 16X as other drive like NEC-3500 does.

i have the same drive, the a17j firmware is the best firmware to date, i have to check out the a70r. The newer firmwares after a17j gave me more errors than previous. I can burn maxell dvd-r at 8x with under 10 pi errors and around 2-4 pi failures. Burnt about 140dvd's to date and not single coaster. GReat dvd burner

can someone tell me about this scanning result by kprobe?

k2000, your Kprobe results look good. You really should run Kprobe at 4x, not "Max" speed. Doing so should make your results look even better. What speed did you burn at, out of curiosity?

I used RIDATA disk +R 4X, burned by my external i/o magic drive 16X (rebadged BTC). I heard so much complaint about BTC drive while I am owning both internal and external BTC drives (iomagic bought at Staples). So I try scanning a disk to check quality of my drive.

Strange with all these people complaining about the btc drive. I haven't had one problem yet with over 140 dvd's and about 80 cd's burned.

That's because people always complain the defect, and less to say what's good. But, the most important is to keep improve the defect, and show more good points.

I wish I could get one that good. I am trying to RMA my second one in 2 months. Neither drive burned more than 50 dvds before they quit recognizing media. The first one stopped recognizinge anything I put in it, this one only recognizes CDs, not DVDs. If I had the money to buy a different brand, I would, as this one is costing me a small fortune in shipping costs and wasted media.
