My writer spins up and down about 4 times before it recognizes the hard drive data to write. I think they call that the lead-in burn time. Mine is very high. My writer is a new Liteon 1673S, I have the writer set to Master and the reader (DVD-Rom ) set to Slave and my hard drive is on a separate ribbon set to master. I hope that is the right config. Does anyone eleses drive spin up and down for about 30 sec. before recognizing data.
