I want to add another SATA drive..or should I say replace an EIDE DVD-Rom with an SATA Blu-Ray burner, but I am totally out of SATA power connectors. I have two on my power supply-one for my hard drive and the other for my other DVD drive. I copy data filed to DVD rom for clients/customers so I need two drives. Any way to convert one of those extra 4 pin connectors to an SATA power connector?
