Win XP Pro SP2 Not Recognizing 320 GB SATA HDD

I just installed WIndows XP Pro on my GA-MA78GM-S2H mobo. I have a 160 GB PATA drive that Windows is installed on. I also have a 320 GB Seagate SATA drive that's not yet partitioned, but I want to use for file storage (lots of video) and the page file.

Two questions:
1. How come Windows Disk Manager only sees 149 GB drive and can I get it to see the whole drive?

2. How do I install the Gigabyte SCSI driver after Windows is installed (I thought I'd set it up during install, but.....)

Hmmmmm...I guess that's actually 3 questions! Too bad.

  1. Windows is reporting 149 giga binary bytes (1024x1024x1024). The drive is sold by the manufacturer as a 160 giga decimal byte drive (1000x1000x1000), in order to make it seem bigger. 149 GB (binary) = 160 GB (decimal). Windows does see the whole drive.
  2. No, sorry that that's not the one I'm talking about. The 160 GB drive is OK. But Windows is only seeing the 320 GB SATA drive as 149 GB.
