The SSD runs fine, no problems there. Initially, I had no trouble finding the HDD in the bios. Windows 7 recognized it, but it didn't function as a hard drive. Disk management picked up the 1tb as "unallocated", so I made a note to format it the next day and went to bed. The next morning it disappeared from windows and the bios, and I haven't been able to find it since. That first night, I did click "populate" - would that have screwed anything up?
