I have a Dell E521 desktop. Recently, my original Dell DVD-ROM has been "flaky" - sometimes wouldn't read. I decided to replace it with a SONY-NEC Optiarc AD-7241S-OB. This is a DVD-RW with lightscribe. When I put in the new drive (leaving the existing original Dell DVD-RW drive-TSST TS-H653A)), the system boots up fine and after a few seconds goes to BSOD. I get the IRQL.... message. When I put the original DVD-ROM back in all is fine. If I put in ONLY the new SONY-NEC drive it boots fine and all is OK, except that the4 system shows it as a generic CD-ROM drive. Through trial and error, it appears that the SONY-NEC will NOT coexist with either of the original Dell DVD drives. The DVD drives are connected to SATA1 and SATA2. I wonder if the problem is that Dell bios does not support lightscribe?

Any suggestions?
