Do you already have one drive working with Windows installed? Why did you order the restore software? If you have windows already on your primary drive and this is a secondary drive, it will not show up in "my computer" until you initialize the drive in "Disk Management". If it is not showing up at all, try another sata cable and a different sata connector on you MB. If you see the drive in "Disk Management" ( in the Windows OS ) right click on the rectangle representing the new drive and choose "format". At this point, you choose the drive letter, the file type, usually NTFS, and the size of the drive. You can partition the drive by choosing less than the total amount, perhaps 500 GB, and then when you finish that partition, you go back and do it again with the remaining size. You can choose to partition it into 3,4,5 or more partitions if you like.
