I got my LiteOn SOHW 1213S

Postby MediumRare on Sun Jun 27, 2004 1:15 pm

Well, I got my LiteOn SOHW 1213S and have been playing around mostly with scans :wink:. I'm not ready to post any results yet, because I've been working on the summary of the latest c't test (will go up shortly).
Here's what it comes with:
  • Quick Istallation guide in 12 languages
  • Nero 6 OEM Suite, 6.3.1.11 (21 April 2004) (was expecting Sonic MyDVD :o)
  • PowerDVD Vers. 5
  • That's (TY) 8x DVD+R disc (YUDEN000 T02)
  • unbranded DVD-R disc (RITEKG04)
  • audio cable and mounting screws.

Here's what the Nero InfoTool has to say about it:

One question- I've been trying to test the transfer rate in CD DVD Speed without actually burning a disc and keep running into this message:

Image

Can someone confirm that this is normal for DVD media (i.e. a simulated write is only available for CD's) ?

+R media cannot be simulated. But -R is okay.

I haven't seen many comparisons of 3S scanning vs. 2S scanning, but there was one person at CDF who posted scans of the same disc scanning on a 3S drive and on a 2S drive, and the 3S reported many more errors than what the 2S drive reported. I'd be very curious to see how the same disc scanned in 3S compares with the same disc scanned in 2S, but I'm guessing that this drive is your first LiteOn DVD writer? :( But nevertheless, it'll still be interesting to see how well this baby works. ;)

Thanks. So I guess I'll have to "Ceate a Data Disc" to check the max. writing speed. :roll:

Yeah, it's my first DVD-burner. I've repeatedly scanned one disc that was burned on another drive (I don't know which one :oops:) and the results are extremely interesting. I'll get that up later tonight after I clean up the summary.

Back to the new toy for now. :D

I think the error rate reported from this drive varies drastically between CAV and CLV. Here are the results from the same disc I scanned with my LTD-163 DVD-ROM (as reported here). I normally use KProbe for scanning, but here I want to show the scanning speed and the quality test option of CD DVD Speed combines this with the PI/PIF plot. First of all, a scan at 4x CLV:

Image

This shows large error counts. Now here is a scan at 6x (CAV):

Image

Note that this starts at ca. 3x, passes 4x at ca. 1 GiB and reaches 6x at the end. There is roughly a factor of 40 between these cases! Here is a summary of all scans I did with this disc. The corresponding results for my DVD-ROM are shown here and do not show this behaviour.

OK I did a data disk. I sacrified the one "Verbatim DLP 8x DVD+R printable, made in Singapore" I had for trial purposes. SmartBurn 3.16:
Code: Select all
        Drive Type = DVD DUAL
         Disc Type = DVD+R (Single Layer)
          Disc MID = 4D 43 43 00 00 00 00 00 (MCC.....)
          Disc TID = 30 30 33 (003)
  Nominal Capacity = 4.38GB
Manufacturer Maybe = Mitsubishi Chemical Corporation
SMART-BURN Speed Limit = 12.0X (Write)


Here is the screen shot for the transfer rate:

Image

So it starts at 6x and goes up to 8x shortly therafter and hits 12x about halfway through.

I haven't put it through the scanning orgy I did for the disc in the previous post, but did a couple of KProbe scans. The count axis is logarithmic so that the differences are visible.
Scanned at @4x:

Image

Scanned at @6x:

Image

So you can see a similar effect to what I mentioned in the previous post, but not as pronounced: reported error rate goes up when using CLV.

This disc is not readable at max. speed on my DVD-Rom drive. Furthermore, trying to copy the data to my harddrive results in CRC errors. Obviously, 12x is too fast for this media.

There's no difference in whe way a drive reports errors in CLV than it will in CAV. The difference is in the readability of the disc at different speeds.

Well something sure is different here- if you look at the CD-Speed scans at roughly 1 GiB, the 6x CAV scan is running at ca. 4x. The PI Sum 8 rate is ca. 10, which is a lot different than ca. 200 at the same position, same reading speed with the CLV scan.

Perhaps Mitsubishi made in Japan could make differences. South Korean distributors used to import directly from Japan but sometimes also from Taiwan and US, via second-tier or even third-tier wholesalers there. Now Verbatim made in Singapore appear more often than the others because they are cheapest.

Well, MCC003 is limited to 8x in the TDK version of the 1213S. 8x in the BenQ 1600 preview that Ian just gave us. And 8x in the Plextor 712A, according to OC-Freak. Guess that means that it's something with the media, if so many companies are limiting it to 8x...

I forget who it was, but someone got the MCC 003's to work at 12x with the Plex.

I agree, it is something with the media. Try telling that to Mitsubishi/Verbatim though.

The TDK firmware T7S1 allowed this media at 12x but was downgraded to 8x in the T7S2 firmware as is the case with the LiteOn firmware TS08...

Well c't also mentioned that Verbatim seems to have a problem in the outer part of the discs. I did a data disc with RicohJpn R02 this evening, also at 12x. The PI-values seem a bit lower, but I haven't had the time to test it extensively yet (scan, transfer rate, whatever). It shows the same funny behaviour with scans at CLV and CAV, though. It'll be Wed. evening before I get around to preparing things properly.

I actually have 2 of these drives until tomororrow and want to do a burn/scan comparison with at least one set of discs before I pass the second drive on to my colleague. I'm just about finished with the one drive now and will go to bed (it's past midnight :o and I have to work tomorrow).

In case you guys missed it HERE, the 1213 has the following hardware:
MT1828E
MT1816E
SAnyo DB11S OPU

Which means it will very likely be flashable to DL and 16x. Time will tell for sure.
