System shows incorrect HD size in OS - Bios is correct 1

[songwritingguy]

Greetings!
I just built my first custom PC and everything is fine with the exception of one problem. I have a 60GB Master HD (Disk 0)that shows 57.2 GB once installed. No problem. However, my 160GB Slave HD (Disk 1)when installed, shows 128GB Unallocated. I realize that formatting uses some space, but why did I loose 30GB?

I've checked my jumpers and they are correct. I thought that maybe the HD was labeled with the wrong size info, but when I go to my BIOS, it does show that it's a 160GB drive. What should I do?

I appreciate this form and how helpful everyone is!
Thanks,
Drew

What OS are you using? With WinXP, for example, you need SP1 to see the full capacity of drives larger than 137GB.

Thanks Island Custom. Yes, I'm using XP, but I've already downloaded SP1. However, someone else said that I needed SP2 to see the complete drive. ???

No, SP1 is all you need. Here's the Microsoft link, I hope it helps:

Problem solved! As it turns out, I actually did not have SP1 downloaded on my XP Home OS. As soon as I downloaded the patch, this slave HD showed 153GB. Appreciate your help and advice!
