Internal HD is reading as "unallocated"  but that is not accurate

I have a 1TB internal SATA HD (western digital) that was formatted as NTSF.
It is being read on My Comp and Disk Management as having 128 gig (that is "healthy" and only openable if I format it), and 800 gig is unallocated.

I used this is my last computer (Xp Pro, sp2) as my media drive, never had an issue with it.  I transfered the drive to a new computer (exact same OS) as the 2nd hard drive and it tells me to access it I have to format the drive.  Unfortunately I have a lot of data on there including my grad school thesis that I can not lose.  

I have read many forums all saying to download drivers, which I already have.

You could also need to update firmware or BIOS on your PC before it recognizes it properly.
