For some reason my NEC ND-6650A (Purchased retail at Newegg.com for my old Inspiron 8100) will only burn my DVD-Rs which are rated at 16x (officially OptoDiscR016) at a maximum of 2x. Also my CD-Rs rated at 52x (officially Lead Data) will only burn at a maximum of 8x. Both discs are Digital Media brand. I’m using Nero 6.6 and checked the Bitsettings for my DVD-Rs using Nero CD/DVD Speed to identify them, then MediaCodeSpeedEdit to check the firmware settings. My firmware indeed only rates my 16x DVDs at a max burn speed of 2x.
Iâ€™ve opened Nero with no disc in the bay and gone through the motions of creating a project until I get to the final page where you can choose the write speed. For my CDs I have options of 24x, 20x, 16x, and a few more. The point being that Nero recognizes the drives capable speeds correctly. However when I put in one of my 52x rated CDs the write speed turns to 8x and goes grey so Iâ€™m unable to change it. The possible DVD write speeds I get when going through the same process (being sure that I have a D5 disc selected and not D9) are only 2.4x, 2x, and 1x. Then when I insert one of my 16x rated DVD-Rs the speed locks on 2x and goes unselectable. This seems to be more of a problem because Nero doesnâ€™t even recognize that my drive is capable of burning a DVD at 8x, 6x, or 4x.
I also have an ND-3500 in my desktop. My 3500 drive is successfully able to burn the same discs at 48x and 16x respectively. Iâ€™m going to go get some new media to further test in my 6650 soon.
So my questions are these:
What could be wrong with my Drive/Firmware/Software/Computer to cause my apparent max DVD write speed within Nero to only be 2.4x when it should be 8x?
Why is my drive (via Nero) downgrading well below the maximum burn speeds once I insert media that should easily meet those speeds?
What can I do to try to fix the afore mentioned problems?
And what type of media do you all suggest I buy to test my drive further?
I did a fair bit of reading throughout the forum trying to troubleshoot my problem, but I’m sure I probably overlooked some stuff. So sorry for any newb mistakes I made, and…
Thanks in advance for the help,
