Optiarc AD-7240S/7241S/7243S Results & Discussion

I have the Optiarc 7240S...I'm new to CD-DVD Speed and have some questions...when using the Nero CD-DVD Speed test after using the 'Create Disc' option to burn I then go under the 'Disc Quality' tab to test but what speed should I be scanning at 8x?

also when looking at people's screenshots in this thread how come under 'Disc Quality' the burner is not the same as the one used to 'Create Disc'?...I'm seeing 'Atapi' or some other burner listed under that tab...aren't you supposed to test the quality using the same burner you created the disc with...I'm confused

Drives with NEC chipset(7240) should use 5x scanning speed, some drives do not scan and some and are not considered accurate. Your Optiarc is OK for scanning but it is not ideal and no jitter reporting which is kinda important a LiteOn is a very good scanner. You do not have to scan with the same drive that burned the disc. Your best test is to run a TRT under benchmark, if it is smooth you can be assured of perfect playback on backups.

thanks...I have a Lite-On LH20A1L burner also hooked up in my system...what scanning speed should I use for that?...I did notice that I'm able to enable the 'Jitter' option when scanning with my Lite-On drive and not with the Sony...sucks that the Sony drives do not support jitter reporting

seems like I'm getting better scores/results with my older Lite-On drive (especially the PI Errors/Failures) then with my new Sony one which is surprising to me...then again maybe it's the media I'm using (Verbatim 16x DVD+R) which likes my Lite-On better

LiteOn A1 series drives typically favor 4x scanning.

If you'd rather, post a scan of discs written with the Optiarc, quality tested with the LiteOn; I'm sure they aren't that bad unless you've gone at them with 20x writing.

For an extra dash of knowledge: those "ATAPI" drives are also LiteOn drives. LiteOn is one of the main brands that we sort of trust to scan with a decent precision relative to how the disc might actually perform. I'd say it's much like how a TRT [as jamescooley1 noted] is the best bet if you only use the Optiarc to test the disc.

The real acid test is to take the disk you make and find the pickiest player you can. If it plays ok in that one it's more then likely a great burn.
You might also want to try different speeds and see which one the burner and disk like with each other. My 1655 usually does it's best burns at 12x with most media, other burners may like full speed or any slower one till you find the sweet spot.
Use the LiteOn to test with and you'll learn what it thinks is a good burn, and what truly is a good burn. That way you'll always have the same platform to test with and you'll see differences right away and they'll be consistent so you don't have a moving target as far as quality scans go.

thanks...I'll post up some scores later tonight...I think I'm going to re-test because it seems I was not doing it correctly...I burned 3 separate discs (one at 8x speed, one at 12x speed and one at 16x speed)...I was using my 7240S to 'Create Disc' and then used that same drive to scan/'Disc Quality' (using 8x to scan)...same thing with my Lite-On LH20A1L...I was using the same drive to burn and scan...I then compared both results to each other

I think I'm going to start over tonight...and burn using my Sony drive and scan using my Lite-On drive...hopefully the results will be better

Thanks for all your help and information...I've learned a lot

the same issue I had last night popped up again...I put in a new disc and when I clicked on 'Create Disc' I get an error message that says "Error! No Additional Sense Information (000000)"...now my entire drive is not working again...this is the same thing that happened last night which made me want to RMA this drive but then this morning everything was working fine again

anyone know why this keeps happening and whether the drive itself is defective or it's some other issue related to CD-DVD Speed...I only have issues with this drive when I attempt to use this program

Could be a defective burner. You'll be asked to install this burner onto a another machine before a RMA is even considered.

it only shows up every so often when running CD-DVD Speed so I'm thinking it has something to do with the software...I can fix the issue by powering down my computer and turning it on again (a restart alone doesn't fix the issue, requires a complete power down)

You also might want to try a different SATA cable and try it in a different SATA port if possible to make sure the cable is OK and that it doesn't have a conflict with the port it's on now with something else.
If it still does it after trying those ideas and putting it in a different machine just to make sure it isn't something with your setup then it might be bad after all.
I had to try three different drive combos on that SATA card I have to find two drives that worked properly togther even though everything would work fine on the native SATA ports.

That isnt normal for any program, for any burner. Try a dif sata cable and then a dif computer

currently it's plugged into SATA port 3...everything works fine during regular use...it's only on occassion with CD-DVD Speed that I encounter any issues so I'm thinking it has to do with that...after doing a Goggle search on that error message I received I found lots of threads about people getting that error in combo with Nero

I'll try plugging it into a different SATA port when I get the chance but since the issue is so rare I might just live with it

Does this drive have problems scanning CD's ?
2 burns , one at 8x, and the other at 48x.
I'm very confused with the scan results

scan by the AD7240S

I know optiarcs are not the best scanners, but are they THAT BAD ?

here are the scans of the scans of the same discs on a 7190S from another PC, and they seem okay.

I've been having very bad burns from an AD7220S in this same PC ( the 7240 is what i got after RMA'ing the 7220)

OK I redid all my scans and have posted the results...seems like the Sony 7240S is the better overall burner versus my older Lite-On LH20A1L...but I do still have some questions

1) is the 'Quality Score' alone the best way of determining the quality of the burn?...I'm asking because although I received a good score of 95 when burning with my 7240S at 8X speed, my 'PI Failures" was 279...when burning using my Lite-On drive at that same 8X speed my PI Failures was a much better 188 with the same Quality Score of 95 (although when burning with the Lite-On all other aspects were slightly higher--PI Errors etc)...I thought that PI Failures was the most important thing to look at in the CD-DVD Speed test (with a 'Maximum' of 4 or less and a 'Total' of less then 400 being very good)

one place where the Sony easily beats the Lite-On is in the Transfer Rate Test benchmark...could not get a good straight line with the Lite-On

2) how is the Quality Score calculated?...it it mostly based on PI Erros/Failures?...because with some burns I get higher Errors/Failures but an overall higher Quality Score, which doesn't make sense to me

3) I going to purchase some Taiyo Yuden media but I heard that the 'Premium' line is the best and not to buy the 'Value' line or any other line that doesn't have 'Premium' listed in the title...is this true?...I can't find any DVD+R 'Premium' Taiyo Yuden media but I did find some without the 'Premium' tag on them...is it worth buying?

I have attached 'Disc Quality' screenshots of burns at 8X, 12X and 16X using my Sony 7240S first and my Lite-On LH20A1L second...the media used was Verbatim 16X DVD+R (MCC 004)...based on those results it would seem that I should be using the Sony at 12X for the best performance?

The 7190 [as well as the 7220] is a rebadged LiteOn, and LiteOn drives don't report as many types of errors on CDs as Optiarc/NEC drives; so your real Optiarc [the 7240] is the better scanner. Your discs don't look like they were written as well as they could have been.

It's only for DVDs that NEC/Optiarc drives aren't considered the best scanner, BTW. CDs are OK.

Nope; the quality score is based on the maximum PIF and nothing else [for these drives], so it alone is not the best. All around, the drives seem evenly matched in those few comparisons, looking only at the scans. All of the parameters are pretty close to one another; not much of a difference to declare a clear winner.

You might have an issue here, or someone may be able to give you some tips; this might deserve its own thread, maybe in the Disc Testing Methods & Software subforum.
See #1

That's probably a question best searched and then asked in the Blank Media forum.

here is my Transfer Rate Test scan at 12X using the 7240 drive first and the Lite-On LH20A1L drive second...the scans at 16X were even worse using the Lite-On drive...pretty big difference

Thanks! Will i have better luck scanning if I crossflash the 7190S to a DH 20A3S?

I have a feeling there is something wrong with the sata connectors/controller in the PC the 7240 has been installed. Two drives cant have the exact same problem. Will try the 7240 on the other system and post results

I finally installed the Liggy fw 1.01bt rpc1 for my Nec-Opt7240S after having the drive sitting on the shelf for months waiting for the bitset fix. The burn is of an ISO of a copy on so-so Ritek F-16 medium +R and bitset. Except what happen between 3 and 3.5, it would have been an excellent burn. Thanks for the help and kudos to liggy for the fw.

No. Not for CDs, anyway.

garmoon, you might try 12x for your burn of Ritek F16.

Can anyone confirm what retail model the AD-7241S is? Is it the DRU-865S or DRU-870S?

Just seems nobody in Australia is doing any of the AD-7240S/7241S/7243S drives, but the DRU-865S and DRU-870S are available.

Cheers guys

DRU 865 is a liteon ihas422 and i think that the dru870 is an optiarc 7240s.
