Thanks, but I figured it out a different way, in case anyone is interested. You click on the drive Properties from the Windows Explorer. Then you click on the Hardware tab and click on the drive caption. For a 150 GB WD Raptor the caption (or name) looks something like:
WDC WD1500AHFD000RAR4 ATA Device
Then click the Properties button and then the Volumes tab. Then populate the Volumes and you have a match of the drive caption and the drive letters. The drive caption is also shown in the BIOS, so you can confirm that you've matched the correct physical drive with both the drive letters and the SATA port.
