I've always used IDE drives, master and slave. The slave went south, hence my need for another drive. I didn't think that a Sata was that different......never had one previously, wasn't even aware of the cabling difference. However, I have the proper cables and it is connected properly at the MB to SATA1.
Not being educated about the Sata, is it possible that they are designed on SATA1 to be the primary drive only, that is "C" drive and SATA2 to be "D" drive, with any IDE drive to follow that sequence/listing?
