Win7 formatted 3TB HD showing as Unallocated on Win8 machi

I'm having a slight problem. My Win7 system crashed and killed two of the 4 drives in it, including the C: drive. I purchased a new Win8 system with a Gigabyte Z77-HD3 motherboard. One of the drives are recognized by the new system (A 2TB WDC WD20EADS), but the other one is a 3TB WDC WD30EZRX, which was a little less than half full. The drive does shows up in the BIOS Setup, and shows up as Unallocated in Computer Management. without a drive letter.
I've come to the conclusion that there is no way of just being able to use the drive, but I would like to be able to recover the files to another drive and then reformat the drive and continue along. I have tried to run Power Data Recovery by MiniTool to try to recover the files, with no luck. Any suggestions would be most helpful.

Thanks in advance.
