I have some troubles with my _NEC DVD+-RW ND-6450A drive. It can't burn a certain kind of DVD-Rs that I've just bought. And I wonder if a firmware upgrade could fix my problem? Before answering this please read through this Thread at VideoHelp, it's not that much to read.

Thanks

Hi & welcome to CDF.

You don't appear to have answered the last question on that forum, what brand are they?
It's quite possible that they're either fakes or sub-standard. In this case the only option is to dump them as a firmware upgrade is unlikely to help.

Also if possible, in addition to brand, can you scan one with dvdidentifier to get us a dye type?

Well, ok. This is EVERYTHING I get with dvdid.

That is everything dvdidentifier tells me. I will looks up what brand it is, I can't check my order since I ordered it with a friend, I will ask him ASAP.

And the brand seem to be: Datamart dvd-r 8x blank

I suspect that is the problem. Own branded media tend to be very sub-standard & not really worth buying.

Well, I have sold half of them today. ^^ So, I just have halv a problem left. :P

Not to a friend I hope.

My brothers army buddy, I don't know whether they'll work for him but... They did on a friends computer so.
