Reports the drive model numbers, the fact that all drives are PATA and other info nicely, but somehow Speccy is confused about the drive size. It says the WD's are 2.5" and they are actually 3.5"

Still, just being able to pull the model and serial numbers off the drives that easily is pretty sweet. I love the real time temp reports in Speccy too.
Good work guys!
