Right-Click on 'My Computer' and select 'Manage'. From there, go to 'Disk Management' and activate, partition, and format your new hard drive. For a separate physical hard drive, select primary partition. Hope this helps.
Help I am having the same problem but I am not given the option to activate my drive or partition it or anything. I can see the drive in the disk Management but it won't let me do anything with it.
