|I don't think the first one is SATA II, but the second (Intel D945GCCR) is.|
Before installing Windows, make sure the SATA interface is set to "AHCI" mode. Once Windows is up and running, and you have the second drive (the hot swappable one) installed, set the properties of that drive to "Optimize for fast removal" through the device manager.
After all that, you should be able to pretty much yank the drive out when ever you want.
