DVD Burner disappears sporadically

I'm so sorry for posting in here... but these forums have been so helpful to me and I'd hate to think I'm about to reformat my HDD when someone might know what my problem is. The other times I got help it was in this CPU forum, and when I posted in the DVD forum it took 4 days just to get a response...

So, while I wait, for what I expect to be a long while, for an email from NEC, I was hoping someone could shed some light on my problem.

I've sent NEC an email, as I said, and am hoping for a response, but past experience with companies I've never heard of leaves me without much hope.

"I didn't know what to search for, so I've been looking at a few of the "DVD Burner Issues" threads, to no avail. Sorry if there's already a thread.

I bought a new burner a few days ago, and it replaced my CD reader as the only optical drive in my PC.

My problem is that sometimes, when I wake up in the morning, it won't be recognized. Sometimes if I put in a cdrw, and click "erase" it will again disappear. Sometimes I don't know at all why it disappears.

When I restart it works fine, but this gets annoying around the 8th time in a day.

This makes no sense to me. I don't know what I have to do. Is there some way to "lock" this elusive driver in place? Is this some ridiculous power issue? I can't figure it out. Would reinstalling windows completely be my solution?

It's a NEC DVDRW ND-3540A, and I'm using an Asus A7S8X-MX mobo. 768mb ddr ram. I've never had issues with my other components before. Running Windows XP Home Edition (Legal, if that matters?)

This is pretty disappointing because I've been wanting to burn a lot of stuff."

If you are using only 2 ide devices, put them each on thier own cable.

The hard drive is on the primary IDE, and the DVDRW is on the secondary. So they are already both on their own cable. :S

Thankyou very much though, as that was 96 hours faster than my last thread's response, and any ideas are, again, greatly appreciated.

You may have a problem with IRQ sharing then. Check for conflicts in device manager. Find out what IRQ your burner is using, then check to see what else is using the same one. If it's a plug-in card, changing the slot may help. If it's an integrated device, uninstalling it in device manager, then re-booting will usually work.

I'm actually suprised. I didn't even know what IRQ was. Thanks very much. My network card and burner are apparently sharing IRQ 17. I'll try uninstalling the card (as it's in the only slot available to it :S) and rebooting.
"brb" I guess.

Alright. I'm assuming it's an IRQ Sharing thing, like you said.

But I can't seem to make it fix by Uninstalling it, and I've run into a few problems during my tries. First I apparently had to re-verify my Windows, and then the next two times my video signal disappeared and I had to hard reboot.

Now that I've discovered this Conflicts Sharing page, though, it looks like I have a ton of problems...

I don't know how all this stuff is being crappy. This is the first computer I've ever built so maybe I just screwed up somewhere.

Any more help would be greatly appreciated.


EDIT: Never mind, I found a different PCI slot. I don't know what I was thinking. I underestimated my little mobo.

Anyway I switched my network card into that slot and now I have:

IRQ 18 SoundMAX Integrated Digital Audio
IRQ 18 3Com 3C905TX-based Ethernet Adapter (Generic) #2

Wow. I... kind of hate IRQ. And I still don't know exactly what it is.

My dvd burner is gone though, so nothing good has come of this. Got it back by doing putting in the windows install cd and letting it load up a bunch of drivers. So it's the same issue as before.<P ID="edit"><FONT SIZE=-1><EM>Edited by 6vx on 09/05/05 02:38 PM.</EM></FONT></P>

Perhaps pulling out that stupid card entirely, and buying a cheap router would solve all these conflicts?

Can't you manually assign IRQs in the BIOS? - Look there.
