In my experience even less reliable than previous NEC drives for Disc Quality Scans on DVD media. I don't use my 7173 for DQS at all.

Disc Quality Scans on CD media can be OK but there seems to be a slightly higher risk of random C2 spikes than with my NEC 4551.

I might consider using my 7173 for DQS on CD media, if I didn't have three drives that are better at the task (BenQ DW1655, Plextor PX-712, NEC ND-4551A).

hi, anyone make a sheep test? i'm looking for a 3 sheep drive
thanks

Hi there, i got a Nec AD-7173A and im getting some problems on writing on CD-RW, i bought 2 Sony CD-RW 700Mb 1x-4x so i burned on them, then when it was time to erase, the option is just not there to press for me to erase, this happened to both CD-RW and the reason i bought these was because this already happened to me with another 2 or 3 CD-RW.
What can this be? should i update the firmware one this?
I use ths original Firmware. Need some help on this.

Thanks.

is this Optiarc AD-7173A the same like the NEC AD7173A ??What about the sata version?so this 1 (in rome there is the nec ad7173)or the pioneer 112 (that got ed choice)??

Hi guys,
I'm very interested in buying this drive 'cos my Lite-On 1693 after 3 years of heavy duty seems to start misfiring a little. I read all good things possible about Nec and Sony drives, still I couldn't find anything about overburning capabilities... did anyone test the 7173 in burning cdrs over 80-81 mins? Can it write also 90 and 100' cdr?
Thankful in advance for any answer...

BenQ and Plextor burners are the only ones that can overburn DVD media.
But virtually all DVD burners support overburning CDs, so you should be on the safe side.

So if anyone would like to make some 16X dvd burning results wirh Lite on quality test
Thanks

Can NEC be used for long lasting quality burns ? cause those peaks in PIFF failures ?

But are those lite on quality scores reliable?

I have NEC 3500 and have these results

SO BIG lite on failures and so good NEC read test

Compared to post above:

WHY when using lite on reader and speed 10X instead of 4X like in post above I get SO BETTER results

CAN someone explain that: it seems LITE on results are not reliable

Compared to NEW nec its VERY veird that I GET better results with NEC 3500 using 8X and 12X writing speeds : without so big PIFF spikes: max 3 !!

Please coud you comment that

Many think that the NEC ND-3500AG was the best drive NEC ever made. In my experience it was good but not as stellar as it has been for some other people. The PIF spike problem has been in every NEC drive since the 3500 AFAIK, but it's worse in some drives than in others - even of the same model.

IIRC, it has even been in the 8x NECs.

what can that 5-7 PIFF peaks produce ?

I have 200 PIFF disks that can be readable

Hello everyone,
I consider buying a new NEC AD-7173A drive but since there is no full review of it anywhere I still have some doubts, especially because I don't have results for advanced tests of this drive.
So if anyone has performed (or is willing to perform) the following tests, please post the results here, I would really appreciate it:
- Advanced DAE tests (copy-protected audio CD's).
- 'Sheep rating' test.
- Overburning CD & DVD.
- Anything else you think is helpful.

P.S. - I've noticed that Liggy has posted a modified firmware that allows bitsetting but someone said that modified firmware may impair the quality of written CD's. Has anyone installed this firmware and would like to comment?

Thanks!

hi, can anyone tell me what DMA mode this drive runs in? 2 or 4, thanks.

It should run in UDMA Mode 4.

thanks, just read that on the NEC site aswell. seems like a good drive, just ordered 1 from SVP with 150 TY media so I shall soon see.

GOOOOOD THING

I am AMAZED:

Verbatim 16X burned at 16X using NEC 7173s 1,02 has this :
Why that happens ?
Can Verbatim have qualitiy problems or ?

What after all that PI error and PI failure means : I used to have very good readeable DVDs with high failure rates compared with this one with 94 quality scan which has "NO SEEK COMPLETE " error..

SO WHATS THE POINT of PI failure scaning ???


Could the DVD be fake ?

I recorded with 18X speed the same DVD media as above and everything was fine..

First at 16X fase no seek complete

Second is readable BUT see graph:

Visualy there is some dark part on the disk, dark "spot"

Now I changed from DEE 1M1 firmware to original 1,02 and everything work FINE:

Maybe Dees firmware has some errors ?

Thanks for those CD-R tests!
