I just reformatted my computer and now it won't recognize my HHD

[opio]

I have a Samsung SSD that I have windows on right now as I just reformatted my SSD and WD 10,000rpm Raptor drive. I had to create a new partition to put windows on my SSD which I've never had to do, now my computer only recognizes my SSD and not my HHD

Go into disk management, and see if the disk appears there. If it does, you need to format it, and create a volume on it, so My Computer can recognise it.
