Could you try this little test and tell me the results :
a) Gather any DATA CD, (use none protected ones)
b) Use the Alcohol software over your GCC-4480B :
Alcohol 120% v1.4.3 Build 158 or later.
(You could go download freely a trial version overhere :
c) Read an image first with datatype = Normal CD.
(You could use Image Making Wizard in Alcohol)
d) Write image over a blank cdr with datatype = General Protected CD
(You could use Image Burning WIzard in Alcohol)
=> You should notice the Write Method = RAW DAO
e) Read back that newly created cdr using the same GCC-4480B device. (It probably wont work !!)
f) Try to read back that newly created cdr over any OTHER cdrom device.
g) You could also try Write Method = RAW SAO + SUB and redo
steps d), e) f). You will probably get same results.
