Received my new GH22NS50 today. Almost returned it since all scans are awful. After tests with many DVD medias and changing some hardware config I found that it doesn’t work properly with SIL3132 SATA2 controller. Tests with sata to usb converter show much better results.

Trying to manage the devices to test with an internal sata ( AMD SB700 ).


#485

Some burns with acceptable quality produced with GH22NS50 TN01.

Verbatim 16x +R ( RITEK R05 ) burned at 12x
Verbatim 16x +R Lightscribe ( MCC004 ) burned at 22x






#486

GH22NS50 TN01

SONYD21 burned at 18x :Z:Z:Z

Looks like the firmware needs much improvement.




#487

GH22NS50 TN01

MCC03RG20 burned at 22x

I can’t believe that the POF is zero. My 20A3P can’t read this disc to test. No trt or quality.

This quality scan is one of the worst I have see consider to the reading curve.

The TRT is perfect with the GH22NP20. :confused:





#488

Thanks for the scan zhadoom :slight_smile:
what LG doing ?


#489

The GH22NS50 performance is worst than the 1st firmware of the GH22NP20.
Any burns using CLV result in huge spikes of PIE and massive PIF. Burns using pure CAV produces acceptable ( not good ) results.

Even 4x/8x burns with Verbatim ( MCC003 = my best media ) produces junk.

I tested RITEK R05 and the only speed the produces acceptable quality is 12x. 4x and 8x produces garbage. With MCC03RG20 there’s no good speed. Any other 8x media ( +R and -R ) burned at 4x or 8x produces disappointing scans.

That’s the worst drive that I test since the infamous Samsung TS-H552U. It’s worst than the TS-H552U because the Samsung burns OK with speeds between 2x to 8x.

Waiting for a firmware update or someone else tests that conclude that my drive is broken.
