Looks like I may have messed up the firmware on my DVD burner:
NEC ND 2500A.
I'm using NERO 6 as my burner program. OS is Win 98 SE.
I flashed the drive with an .exe flasher of the newest firmware, 1.0b, from NEC. Everything seemed to go well. Nero's Info Tool says I have the firmware installed.
The drive works, except:
"My Computer" or "Explore" shows the drive as a CD burner, not a DVD. Any DVD media put in, gives zero for the available size. CD media, shows size used and available, correctly.
Checking the Control Panel|System|Device Manager, under CD, the burner is listed (at list its name) and says the driver is loaded and is working properly. I guess that's correct, but the firmware has turned it into a broken, DVD burner.
Even though, the OS doesn't recognize the burner as a DVD, I can burn to DVD media; but only once, regardless of whether or not I set it to burn in multi session or session-at-once. Even though I should be able to burn more, the media is finalized.
After a DVD media burn though, , the OS reports the space used, but still the available space, as zero.
I reinstalled the firmware; reinstalled Nero; flashed the firmware again; flashed the firmware back to the original; tried different blank media as well as recorded media; moved the burner to a Windows 2000 computer. Nothing made a difference. Each OS shows I have only a CD burner. So, it has to be the firmware, right?
Searching Google, I found others had a similar problem. A couple of people reported the problem was fixed by flashing (as NEC instructions say) in "Safe Mode."
But, in Safe Mode, no CD drivers are loaded (nor are the video card or mouse drivers). If the CD drivers aren't installed, how is Safe Mode going to find the device?
I put the firmware on a floppy and ran it anyway.
The results were an error: ASPI32 Target not found [Target NEC ND-2500A is not found correctly].
Which I guess isn't surprising, since Safe Mode sees no CD.
How do I get around this, so I can flash in Safe Mode? Is that the answer?
Since some found that to correct the problem, how do I fix this so I can flash in "Safe Mode"? I have no clue as to how to get safe mode to see the burner and get ASPI32 right.
Or do you think there is another reason for the OS not reading the burner or the media as DVD?
Having tired the burner on two computer, with different Operating Systems, to me, that points to the firmware. But maybe I'm wrong.
On a web site, which I can't find anymore, it listed all the firmware for NEC burners:, in the original form from NEC, and a binflash form for DOS (and I think Linux too).
If I can't fix "Safe Mode," ASPI32 and not seeing the CD problem, would it be possible to flash from a DOS boot with CD support?
If so, does anyone know where that web site is? Or, where I can get the firmware in DOS?
First though, I'd like to be able to flash from "Safe Mode." If you think that is the answer.
I'm shooting in the dark here. --
