did you format the drive with both disks in place or just the one?
Try removing the XP disk and restarting? What happens then?
With SATA you don't have master/slave. Each disk has its own controller and is defined as a master. You need to select the boot order of the hard drives in the BIOS.
However as the drive isn't being seen it suggests either
drive not connected
drive not formatted correctly
bad drive
disabled in BIOS
things are confused by the way Win7 will create a bootloader partition onto a drive other than the system driver during setup if it finds one - hence my first questions
PS - just what hard disk problems were you getting beforehand?
