|"I am running Vista natively on Mac", so you are not running Mac OS at all? No Virtual Machines correct?|
Sounds like you need to find an SCSI driver for Windows that supports your MAC. I am assuming you are using SCSI CD/DVD ROM because most Macs use SCSI drives but if it is SATA then it should work. Find out what kind of drive controller, Make and Model you are using for the Mac and Google it for drivers.
