Do I have to do something special to make the C2 pointers work from an external drive enclosure? I have successfully used this disc to detect C2 pointers in the past, so the disc isn't the problem. This drive is supposed to have C2 pointers, but dBpoweramp is not detecting them with a CD that is purposely defective (using the magic marker technique described in the setup guide). I have a new CD drive (Asus DRW-24B1ST j) in an external USB enclosure (Vantec NexStar DX NST-530S3-BK).
