Does your motherboard have an SATA connector? Or are you using a controller card?
As far as setting master or slave on a drive, there should be a legend on the top of the HD. Jumpers are usually used to set master and slave relationships. Cable select is an iffy deal.
AFAIK, you cant set the IDE drive to the slave on the same chain because IDE and SATA use different connections and different controllers (dont know if thats what you were asking or not, but thats what it seemed). What you COULD do is setup your C drive as SATA and later on invest in another SATA drive. The D drive can be a slave on your IDE chain with your CD-ROM (for now). But I think that would pretty much rule out a RAID setup, if thats what you were shooting for, until you can get a second SATA drive.
