hi caleb,
About your cd-burner, you can rebuild your links sg0 and sg1 if they are still missing:
# ln -s /dev/sg0 /dev/sga
# ln -s /dev/sg1 /dev/sgb
If /dev/sga or /dev/sgb are missing too, you can recreate then:
# mknod c 21 0 /dev/sga
# mknod c 21 1 /dev/sgb
Besides, they are a Generic SCSI access, so the most indicate devices you should use are /dev/sr0 and /dev/sr1, because they are SCSI CDROM devices
I hope this help you out
