Some scans from the new LG drive.
How's it look guys?

[Charlie]

Some awesome scans indeed. Had to move the post as no one could reply in that locked thread. :)

[Ralph]

Is the purpose of the nero is to see how fast the LG, is or what, I am still in the dark ages just seen Marlin walk by.:thinking:

[Smduff]

the purpose of scanning is to see the quality of the burn basically Ralph I myself just like to watch the movie to see how it worked.

[Ralph]

So how can you tell the quality by what? Learning my friend.

[kipper]

The two benchmark (TRT) scans look good, the quality scan will not tell you much since that drive is not capable of providing anything meaningful.

If you have a lite-on, BenQ (1620-1655), or an Optiarc do the quality scanning with one of them.

Be interesting if you provide a scan of the Burn, the TRT, and the QS on the same disc. You could use a Disc Image of a movie backup and burn it with Nero CD-speed and provide a snapshot of that graph for the burn. Then do the TRT and QS with an appropriate drive.

[HemiDog]

Just bought ( on line ) the following:

Lite-On IHAS324 Internal DVD Writer - DVD+R 24X, DVD-R 24X, DVD+RW 8X, DVD-RW 6X, SATA

I should get it on the 20th of this month. I will then attempt to do what kipper suggested.

[kipper]

The iHAS/P drives will be great for Quality Scanning with CD-Speed Version 47716. ([Only registered and activated users can see links] ols%2FCDSpeed-SE3-47716.rar)

Hi :)
Yep CD/DVDSpeed is certainly finely tuned for the Lite-On. :naanaa:

:giggle: :wink: :giggle:

Scans looks ok. That first huge pif at 27 is either a miss report or something that could be a problem.
Watch the title for the ultimate judgement.
Keep the disc and maybe re scan it when you get the liteon.
But at 100 total pif's thats awesome.

Hi :)
[Only registered and activated users can see links]
Initial spike is often caused by drive mechanics, not necessarily burn quality.
Trick to eliminate this!
Run a burst rate test immediately prior to Disc Quality Scan.
The volume of data means that you really should get a good result.
It is only the last 25% or so that will really show any irregularities that maybe of significance.
Although a crap burn & or media will give poor scans regardless.

[Smduff]

I have messed around a bit with scanning as many have but don't completely understand it. I would like to see a scan tutorial giving a full explanation of what is seen and how to interpret what shown by the scan. If one of you guru's has the time.

[Charlie]

Me too as I know nother really most of the talk is Greek.

A very fine article on Home Quality Scanner which covers not only CD-speed but K-probe and Plextor Utilities can be read here ([Only registered and activated users can see links]).

I think this will help inform you; should you have more questions after looking the article over please ask, I am sure there are members here that will fill in the blanks.

Written in 2006 but basically holds true today.

Hi :)
As you point out it is now somewhat dated.
The comparisons between different drives is almost irrelevant to most users.
With no more genuine BenQs or Plextors.
The using of more than one method (s/w) to perform tests.
To me (& I am biased) is a bit of a smoke screen.
Pointing out BenQs scanning irregularities, yet playing down (to some extent) Lite-Ons.
The problem of consistency.
Too many imponderables.
Quality of domestic main supplies.
This can vary almost constantly.
Power Conditioner (not power filters) are helpful in this area.
But are expensive.
Temp of internals & the external not monitored.
Temps are or certainly can be very important.
I am sure that some folk scan the same disc, till they get the desired result.
This of course is a forum phenomena.


Also the fact that you can have a good scan, that doesn't play well.
Occasionally won't play at all.
Then there's the reverse.
Where a seemingly total blowout.
Will play often without any visible problem.

[zebadee]

Hi :)
Interpreting & understanding scans is a lengthy process.
So much of good interpretation is about knowledge of setup, media etc.
This can be seen as familiarity of a sequence of events.
Some might call it delusion.... :wink:
Probably why no-one has really produced the "definitive" guide.

[kipper]

I think a couple of the members here still have the PX760 and some will still have a BenQ or two. Thats the only reason I provide the link to the article.

By all means, quality scanning at home is very subjective and subject to each individual set up.

To me the most informative scan of all that can be done at home is the Transfer Rate Test; should you have a disc that play poorly or not at all, you can see the read problems from the scan.

The main reason I use quality scanning is to determine the best possible burn speed with the media I am currently using; the quality scanning will give you an idea of what is the best burn speed for your system with a particular drive, media, etc....

Hi :)
In response to post # 17.
I tend to assume* anybody with a BenQ has already got into scanning.
Certainly a lot, if not most Plextor owners have.
So I was referring to the (true) novice.
The only reason for having a Lite-On is to scan. (My opinion).
From the 1620 > 1655. BenQ were not only better but faster readers (just).
Scanning Lite-On has problems measuring jitter, especially DL.
Most can't cope with layerbreak.
As for CDR scanning, you might as well toss a coin.
Whereas BenQ & Plextor haven't any such idiosyncrasies.


*Making assumptions is a fools tool. :thinking:

[zebadee]

Hi :)
Compare this scan to the one in the OP.
Note scanning speed is 4x,
[Only registered and activated users can see links]
The only reason to up the speed, is to encourage more folk to use this approach. (My opinion.... again :rolleyes ).

[Only registered and activated users can see links] ([Only registered and activated users can see links])

Things of particular note are ...................
PIFs (PIEs are errors but most are correctable).
Jitter (I personally don't like [or want] the max to be in double figures).
Quality score to be between 93 <> 95%.
So the above just scrapes in...... :cool

[zebadee]

Hi :)
TRTs can be enlightening.
Having introduced some problems to disc surface with sharpie.
See how Lite-On (note I got fed up with the progress) compares to Samsung.

[Only registered and activated users can see links] ([Only registered and activated users can see links])
N.B. The lag at the beginning is typical.
[Lag is often seen as errors when performing a Disc Quality test.]
Again doing a Burst Rate test 1st eliminates this.

OK here is a full TRT from Lite-On (after Burst Rate test).

[kipper]

If you care to scan CD-R/RW media it is best if you can find a Lite-On CDRW 5238 or earlier model.

You can do a decent CDR Scan with the BenQ if you use Advance Qual Scan but still very subjective to interpretation.

[Charlie]

I was going to get a Lite-On for this but the one I wan is sold out :) I have bought 3 sammy drives and each time the door always sticks after about 1 year or so. So I need a good reader as well.

which Lite-on were you looking at Charlie?

Any of the iHAS/P will work nicely for DVD scanning.

SOLD OUT:giggle:

[Charlie]

Yep they are in demand I guess but the free shipping helps being sold out too. Thought about a Sony Optric but will have to see what Kipper says. I kinda want to play with sanning and use the jitter and such too.

If its for scanning then wait Charlie. Liteon is what most is optimized for now days.
You have enough Pioneer and LG's for burning quality media.

Scanning/Reading I'll wait for now though.

Charlie, I have a nice DH203AP with the best firmware from CodeKing for scanning and reports Jitter on all DL media, let me know if you are interested.

[Charlie]

I'll keep that in mind kipper, thanks.

Hey Dog

If you are to trust home scanning; when scaning for disc quality with the Lite-ons scan at 4X, with the BenQ scan at 8X.

Just a thought is all

Still a very good burn.

Did you select Jitter in the Advance button??

That drive should report jitter.

You can also download the free jitter setter program and fine tune the jitter scanning also.

[Ralph]

Hemi, does your above results show a better result at 4x????

[kipper]

Here is a link to the jitter tool, set it for 4X with the lite-ons

Kipper the best Jitter tool is a brewski a few of them and then you will be set for the night.:agree:

Bit of a strange burn really. A tale of two. The pie is questionable and could cause problems with playback , especially on a picky player as we know. In my experience though for my personal setup that should play well.
The pif are very good , nice and low with no nasty high spikes. More importantly for me it was continuous of the the pattern.
