I have nothing on the Primary IDE, the DVD/CDRW on the secondary IDE master and the HDDs on the third IDE master and slave. Also, due to the initial problem the operating system and programs are installed on the drive which is the slave.
The machine is a Pentium 3GHz dual core running XPMCE and has two serial ATA 250GB hard drives.
I am currently trying to get all this sorted out with the manufacturer, but I don't know if these things are issues or if I'm just worrying over nothing? Frankly if these things affect performance then they must be fixed.
