Well actually, I used a different disk and now everything is ok but for some reason XP keeps asking for the product key and will not accept the one with the disk. In addition, the lite-on dvd burner is still not function.
I have a different board but am having a simillar problem with my optical drives. I know it's not the drives because I got a new one, swapped them out, tried with only one installed...slave/master/CS...basically tried everything under the sun.
The drives are installed, they are there in the BIOS and in Windows. They are fully functional in Device manager, show up everywhere correctly, etc. etc. BUT they will NOT read discs when they're inserted in them. IF you go to "My Computer" and double click on the drive with a disc inserted, it will say "Please insert Disc" or it will show the disc as blank. Have tried different CDs, CD-Rs, CD-RWs, DVDs, DVD-Rs, same result.
The only time they WILL work is when I right-click on "My Computer"-->Manage-->Disk Management. When I go there, both drives "come alive", start spinning and all of a sudden the very disk they were showing as blank has files on it! MAGIC! :x And these aren't burnt CDs, but actual software CDs.
I have to do the "Disk Management" trick to make them work everytime I need to do read off the disk. Meanwhile I have been unable to figure out why this is happening. My only guess is MOTHERBOARD, but I am not sure.
