Even if a device is supported in Alcohol this does not mean that this device is capable of handeling all copy protections. In SD2 for example your drive needs to be EFM capable if not you will not be able to create a working back up, some drives can do this with the Enable EFM option but not all drives.
Its like expecting an un moddified playstation to play a backup disc.. it will not do it
There is a list of known drives and their EFM capability on the Alcohol Support Forum, i suggest you check it out. if you drive is not listed then download the test that you can find there and test your drive, let support at Alcohol have your results and they can then add your drive to the list and state if it is or is not EFM capable.
