I have three HDs. Two PATA drives and one SATA drive. The Master PATA drive has the OS. Does it matter where the OS is installed? If it doesn't I can leave it where it is but if does, I'll have to go through the lenghty process of clean loading the OS to the SATA drive and systematically load the various upgrades such as SP2. I plan to temporarily remove the existing drive with the OS and make a clean load. When finished, can re-install the old drive with the OS and transfer the update files? NOTE: As it is now, Windows won't allow me to load the OS citing that the existing copy is more updated than the copy on the disk.
