NEC 3500A Questions

Hello, This is my first time posting and I have some questions regarding the NEC drive.

I’m using CopytoDvD ( and Ritek Media (R03-02) on my NEC 3500a, the program tells me that the Max speed that I can burn is 4x, would that be correct?

I have upgraded the firmware to version 2.17 w. the Windows Flasher.

Is there a way that I can unlock it?

I’ve also noticed that there is a new firmware version 2.18 from , should I upgrade again?

Please advise.

Can anyone recommend a good .img program for me to burn my images?

Try DVD Decrypter
