Media recognition error

Here’s a recent error message from a session where I am trying to write a DVD to a fairly generic brand of media (I bought a 100pk of these, but I have to relegate use to my dvd recorder). :frowning:

here’s the tech description of the media

I’m using a ND-3520A. I got binflash but does anyone think that the newer bioses (and if so which one) would fix this situation so that I can use these disks?

@ David E. Fox,

I believe the problem you are experiencing is that your NEC ND-3520 version 1.04 firmware does not recognize your ISSM RO2 DVD-R Media.

Suggest updating your NEC ND-3520A DVD Burner Firmware to the newer version 3.06 firmware. Suggest visiting Forum Member ScorpioSoft’s NEC Firmware Page ( and look on his NEC-3520 page for NEC ND-3520 version 3.06 firmware ( Then look on his NEC Firmware Utilities page for the NEC Flash ( flashing utility.

Best Regards,

ISSM R02 is supported in firmware version 3.06 at 16x which you can get from NEC’s website, or if you don’t mind using modified firmware, 3.06 and 2.U3 is available here

oh good :slight_smile:

grabbed the bin file - and used necflash on linux to flash the 3520a - great job
issm r02 at 16k speed… works ! :slight_smile:

writing now…
