Hey, first time actually posting since I have a problem.

I recently built a new system, and I have 2 sata drives installed now that run great, those two are an older Hitachi Deskstar(I think that's the name), and a 150gb WD Raptor. I recently, as in just now, got in a Samsung Spinpoint 1TB drive. Windows doesn't recognize the HDD, although I can pull it up in the BIOS no problem. If it matters, I have the Raptor as my boot drive in the Sata 1 plug, the Deskstar in Sata 3, and the new Spinpoint is in Sata 5. Help!?

My system is:
CPU:Intel Q6700
Mobo:Asus p5n32-e
-HDD(s)-
Sata 1 Slot: WD 150GB Raptor
Sata 3 Slow: Hitachi 160GB Deskstar
Memory: 2GB OCZ Platinum DDR2
Graphics Card: BFG 8800GTS 640

Right click on My Computer, -->Manage. Choose Disk Management. On the new hard disk, right click--> Identify. You should have be able to partition it after that

Alright, so I can see the drive, thanks, but only in the management page and it says "Not Initialized" I am assuming I have to right click it and initialize, it then gives me the options to Initialize with:
MBR (Master Boot Record)
or
GPT (GUID Partition Table)

And it mentions that GPT isn't recognizable by older versions of windows, and is for drives over 2TB, this current drive is 1TB.

Again, thanks.
