Actually, the boot DVD reads & boots just fine (wrote it on the hdc drive), it just doesn't automount. > Can you read a CD in the failing drive? Yes, also DVDs, data or movie, no problems. > Have you been monkeying around with the kernel? No. I have NTFS r/w support built in, but no other mods. > Is the "DVD drive" really a DVD drive or is it only for CDs? hdc is an Emprex 16x DVD+/-R D/L DVD/CD burner; hdd is a Hammer (Matsushita) 16x DVD+/-R D/L DVD burner. Both work fine for almost every other CD or DVD I have burned in either drive, it's just this one data DVD that seems to have gone bad since June 9 when I burned it. FYI, the DVD is question is a TDK 16x +R DVD. I may have burned it at 16x, although I've noticed that for movies and best compatibility, 12x works better in the Emprex and 8x in the Hammer.
