My computer is a Toshiba Qosmio X875. It came with two 500gb hard drives. It's running Windows 8.

My old computer was some old Toshiba Satellite. It had a 640gb hard drive. It ran Windows 7.

After plenty of wear and tear, the old Satellite died on me. I want to move some things on the 640gb hard drive from that onto one of my new drives. However, when I replace the extra 500gb in the Qosmio with the 640gb drive, it isn't shown in My Computer or Disk Management. When I open up BIOS, the drive is visible.

I've searched around the web and there are plenty of solutions that either don't work for me or I just don't know enough about what I'm doing to find what I need. If it's a simple driver issue, I have no idea where to go, what to get, or even what to look for.

I'm not too computer savvy, so please walk me through everything as if I'm a young child.

I was thinking about getting a USB Adapter for the Hard Drive and hope my computer can recognize it then or at least have my roommate's computer recognize it and move the data over to his machine, but I wouldn't be able to go pick one up for a week or so and I'd very much like to get this done sooner rather than later.
