Did you get a manual with the DVD? If not on the rear of the unit you should see some pins with some caps on them, these are the jumpers. It may show you on there where they need to be placed for Master or Slave.
If not you might try a GOOGLE
search entering the brand name and numbers. If you cannot find post those back and we'll see what we can come up with.
The resaon I asked if I could change from secondary slave to primary slave is becuase on boot up the DVD/CDRW is shown as secondary slave but does not show up in My computer or the Device Manager in the properties
Thanks for the original helpful reply
