[qanda]This thread is about the Optiarc AD-7200A. Click here to see full specs[/qanda]Folks,
I already have a burner ND-2500A installed. Mainly I use it to burn Video-DVD's on re-writable media. The software I use is TMPGEnc DVD Author 1.6 with integrated burning engine.
When I insert a DVD plus RW capable to be used at burning speed 2,4 and 4 the burnig engine also let me select 2,4 or 4.
When I insert a DVD minus RW capable to be used at burning speed 1 and 2 the burnig engine also let me select 1 or 2.
When I insert a DVD plus R capable to be used at burning speed 4, 8, 12 and 16 the burnig engine let me select 4, 6 or 8. Not higher because the burners max speed is 8.
Now I bought a AD-7200 P-ATA (firmware version 1.09) and installed it additionally. Now it is no more possible to select different speeds for RW-Media (the ND-2500A still can). Only the max speed is possible to use. For instance, a minus RW for speed 1 and 2 is burned with 2, a plus RW for 2,4 and 4 is burned with 4.... I don't like this very much, because using RW with highest burning speed results often in drop outs and data failures. So I'd like to use the lowest burning speed available.
Only with R Media I can still select 4, 6, 8 and 16.
I tried some other burning Programs, WinOn CD 6, Ulead Burn Now 4.5, CyberLink Power2Go v6.0 and RecordNOWDeluxe.7.3. Same behavior.
Technical Support said:
"Drives of the AD-series have be designed to burn at the best maximum speed if recommended media is used. When media is inserted in the drive, the drive does a speed check and laser calibration. The real burning process then starts after this process. Should the laser detect a section that does not match the calibration, the speed will automatically be reduced. Unfortunately, there is no firmware available to change this process (for RWs). The speed modes offered are those the drive determines best for the writing process."
It's not really helpful for me
If it works as designed, I'll give it back and buy some other ....
