Apple's OEM CD drives are rather unique in that many of them use selective termination. With the term power jumped, the CD drive checks the SCSI chain and decides if it needs to have termination on or off. It then automatically sets itself. if the drive is at the end of the chain, it will terminate itself and if in the middle, turn termination off. I have noticed that with some other devices the CD drive doesn't know how to terminate properly. (possibly due to the ROM in the new device not being supported by Apple?)
