[CentOS] Problems with SATA DVD+-RW drive [SOLVED]

[Jay Leafey]

With a lot of hints and a little research I figured out how to get my 
SATA DVD burner to work.  The biggest clue was in the Nero for Linux 
documentation which stated that the /dev/scd* device was only used for 
READING from the drive, that writing is done via the /dev/sg* device.  A 
quick look showed that the /dev/sg devices did not exist on my system. 
After doing a 'modprobe sg' they did exist and both cdrecord and 
growisofs work just fine.

In order to make this fix permanent I added the following line to 
/etc/modprobe.conf:

install sr_mod /sbin/modprobe sg ; /sbin/modprobe --ignore-install sr_mod

When the system detects a SCSI (or in this case SATA) CD device it 
automatically loads the sr_mod module to service the /dev/scd* device. 
This addition forces the sg (Generic SCSI) module to be loaded whenever 
the sr_mod gets loaded.

Hope that helps the next guy!
