Chewy's New Nec 3550

[Chewy]

The drive I received is actually a very good burner and a more than
adequate scanner, contrary to what I have read over at cdfreaks(scanning).

To test the scanning ability I used media(sony/made in japan/8x dvd+r)
Disks were burned at 8x in the nec 3550(latest and greatest frimware/
modified)

This created a 99QS baseline to work off of.

Now the first disk scanned with the NEC showed a bad burn or scan
in the first gig. This area dropped QS to 95.

The second disk scanned gave a little rough area in this part but kept
the QS of 99.

Now here's the catch, the same dvd's scanned in my best scanner,
looked great in my Benq 1620.

I discarded the first scan by the nec as I thought I had a bad blank.
The most important part of the scan PI Failures is very similar
between the two scanners. You can almost totally ignore the top half of the scan, the PI Errors as the nec 3550 reports way too high a value here.

here are the 2 scans by the benq of the nec burns

here's the scan by nec of burn 2

[Chewy]

here's burn 3 scanned with both drives
PIF's superimposed QS 97 and 98
pretty damn reliable

Chewy, same one you refered me to. http://liggydee.cdfreaks.com/page/3550/
the 1.y4 org?

[Chewy]

mill,
yes, but it's also in the nec scans I posted identifying the scanner and speed of scan.
Let's see one of yours!

Tell me how, and with fujifilm or verbatim or imation dvd's. This will be fun.

Ok

[mill]

What you think?

[Chewy]

for a scan make sure you burn at 8x only,

let the scan finish close the top window and use the little icon(floppy)
to save as png.

getting there tho

Thanks Chewy, now thats with the firmware that came with it , i see yours are a little better, why? plus i did my scan with the nec, i didnt know you could do the scan with a different burner, did not think it would read true. Thanks I learned somthing today. What should a good scan % be between?

[Chewy]

what speed did you burn the verbatim at?

4d 43 43 00 00 00 00 00 30 30 34 00 01 -> [MCC 004 ] 2.4 4.0 6.0 8.0 12.0 16.0
I don't pretend to understand this

firmwares are based on the same write strategy(see above)
I assume modded firmware allows bitsetting and region free

[mill]

either at max 16x or i selected 8x I dont remember ,why?
PS i dont understand any of it. The results of the scan that is. and that the verb. was 1% less that might be do to the 16x burn? And also verbatim must be cmc? No i take that back I see MCC004
