2.4 G P4 running XP Home with 80G Maxtor HDD. Master on Secondary IDE is DVDRW drive, and slave is CDRW drive. Clean iinstall of OS, get recording tab in properties of each drive, but if you check one to enable recording, the other one unchecks. XP only supports 1 burner? No cd authoring software except the built-in XP stuff. Both drives will make a cd, just the strange thing of enabling recording in the properties.
