Hello, Where in the led ribbon should the master or slave be set at. Is master at the end of ribbon or the beginning connection. I have two new dvd light scribe players as old one was not reading and copies were often not good all the way through.

ITS on the drives in the back!Set it to cable select and it will set it up for you!
Typically the end one is primary and the middle is secondery and the drive jumpers set accordingly, otherwise as area51reopened said set both to cable select.
