I think Liteon uses optical lens equipment different from eachother mostly.
Because according to my tests :
It is not due to the Recalibration Data.
I copied my friends Calibration Data from his Liteon 812S to mine.
Still too different PI and PIF Results for the exaclty same media.
It is not due to the firmware changes.Even Strat Changes.
Princo — > Princo8X2 Strat works very well with his Liteon 812S
but not mine at all for damn reason.
So whats left ? There is nothing different about software part.
But it seems there is something different about Hardware part !
And what do you think this different part is ? According to me,
Electronic circuit should be exactly the same but only one thing
may be different.
Optical Equipment ? Yes. I believe.This is the thing that makes
the same model of a Liteon,different from one another.
Well but still your ideas are greaty appreciated.
And one other thing.Do you think this happens in NEC DVDRW Drives ?
or other drives ?
