Secondary HDD not visible Win7 64bit

[Karz1993]

Hi everyone,
I recently baught a Clevo Metabox P170EM laptop (the Australian version, i think the US version is by Sager), and it has a 128gb SSD Crucial M4 and a secondary 750gb HDD. I am not actually sure what kind of harddrive it is, all I know is that it is 750gb 7200rpm.

I baught the laptop without an OS, as I had a Win7 disk already, and I had to go into drive management to format the secondary HDD. That all worked fine, I got it up and running, and was copying data across for a day. I also installed a couple of games (Crysis 1 &2, Dragon Age Origins if it matters) and played them from the secondary drive without a hassle.

While playing, I got 122 Windows Updates which required a restart. So I let them install while I worked on clearing up my old laptop.

Next time I booted the new one up, all of the icons for the previous games were blank and the HDD was unavailable. It doesn't show up in My Computer or Disk Management or even the BIOS (is that normal?)

It also seemingly uninstalled some of my drivers - my nvidia GTX 670M wasn't recognised til I reinstalled the driver from the CD. I tried reinstalling every driver but no luck for the HDD.
How do I get access to my secondary HDD?

So the BIOS doesn't detect it? If that's the case then it might have disconnected from the laptop it self. The Updates wouldn't have disabled it from the BIOS.
