I have an issue with a new build. My DVD RW is connecting to the mobo via a ribbon IDE cable. My sole HD is connecting to the mobo into a SATA slot, SATA1 from five slots (2, 3 ,4 ,5) Problem is, the HDD is not being recognised. It has the DVD as master with the Slave unrecognised. Hope this all makes sense. How do I fix it?
