Sorry, no feedback at SonyNec Optiarc site. I have very new 7173a. And I faced up with big problem.
No probems wrighting DVD. No problems wrighting CD-RW. No problems wrighting CD-R without overburn (except reading speed no bigger than 40x, though writing speed - 48x - littlebit strange).
I have tested overburn using Nero and Nero said I can write 82-00 minutes. But - no! It is wrighting with no errors but last tracks are not readable. I use TY and Phillips CD-Rs - all the same.
When I use CD-RW - all ok, readable!
Why I can write CD-RW with overburn but cannot write CD-R with overburn???
I checked Phillips CD-r on other PC with Optiarc 5170a - all ok without any errors. My optiarc 7173 is new, I used it for recording no more than 15-20 times…
The Nero test screen after burning is attached. All 3 times test results are absolutely same (as in attached picture). When usind CD-RW - normal result without any strangeness…
I cannot understand: is my drive not perfect or - what???
PS: previously I used NEC-3200 and did not have any problems with overburn and readind speed…
PPS: This is readable disk test but also looks very strange! (PIC 2)
Please give an advise who knows something about this problem…
