Windows 7 not detecting Hard Drive

I had 3 hard-drives (all SATA) in my PC: 1x 300GB and 2x 500GB
I recently bought a 2TB hard-drive (also SATA) and swapped it for one of the 500GB hard-drive (as I didn't have any spare SATA ports left - my CD/DVD Drive is also SATA).
BIOS recognises all 4 drives (CD/DVD, 2TB, 500GB & 300GB), but Win 7 only recognises 3 drives (CD/DVD, 2TB & 300GB), the strangest thing is that it recognises the new 2TB hard-drive, but now the old 500GB drive won't show up (both in 'My Comp' and in Disk Management).
I went into BIOS and got it to re-AUTO detect the hard-drives, and it definetly is picking up all the drives correctly and I tried swapping the cables from the 500GB with the 2TB, just in case one of them wasn't connected properly or so forth, but I can't get Win 7 to detect the 500GB hard-drive.
BTW, Win 7 is installed on the 300GB.
Any suggestions...?
 
Is this a dynamic disk?

I believe you need to import the foreign disk when they are moved from another computer, although this is not your case, this may solve your problem.

Go to Administrative Tools from Control Panel and then Computer Management, select Disk Management from the options on the left, from here you can import the disk.
 
What motherboard do you have? It's possible that you have 2 separate sata controllers and would need the driver loaded before the system can actually see the drives.
