So, I just got my new NEC-3520A and installed t into my computer. When I do, my DVD rom drive starts to error out also. Wat the heck is going on? Now it says the devices aren't even detected. I removed them and then put them in again. I changed the place where ur suppose to plug it into the motherboard. Nothing works. I dont know if it conflicts with master/slave stuff because I have a S-ATA HDD... but my comp has been working fine for a few months now. I dont know heh. WinXP SP1 Athlon64 3200 1024 MB crucial Ram

The SATA drive has no effect on the IDE channels. You may have the jumpers on the optical drives set wrong.

Jumpers? How does that work, and it(the dvd rom) worked fine before I put in the NEC dvd/rw drive... My other one is an asus dvd rom

"I dont know if it conflicts with master/slave stuff". That is what the jumpers are about. Looking at the back of the drives in qusetion you will see a group of pins at the left rear. On top of the drive adjaccent to those pins is a diagram to show the jumper positions for different settings. If those drives are connected to the same cable and those jumpers aren't set correctly, the drives can conflict. There are three posibilities. Master, slave, or cable select (CS). The best choices IMO are a combination of Master and slave. I'm too lazy to look up the drive you mentioned by model so I will assume this is a burner. Set the jumpers on that drive to master and the other to slave. Now it won't matter if you use the center of end connector on the cable. Just use whichever one works best with the cable. As far as the cable goes if you received a new cable with the new drive, install that one. The end of the cable with the longer space between the connectors goes to the MBoard.

i dont know the answer but from memory i think i have seen the answers to this on the microsoft website. go to www.microsoft.com , have a look at the Knowledge Base and put the error code details in the search field. I have found this to be a very good way of finding solutions although i sometimes find that it is written in a technical way that is sometimes a bit beyond me.

Check your BIOS settings to make sure the drive is enabled. Sounds like incorrect cabling connection.

If all your cabling is set correctly,and the drives still don't appear in Device Manager it could be an XP Registry problem. I found this,use it at your own risk.
