Ah, I didn't know DiskPart would do that. Thanks Roger. I've used DiskPart to create some extended and logical partitions on the HD because as far as I can seen, the windows disk management software now only allows for the creation of "simple volumes"? (what the heck are those?) This new WD 2 TB drive is my data drive. I've bought an Intel SSD to use as my primary "OS" drive... works wonderfully with Windows7.
