what does the bios setup see the drives as? Partition utilities won't be able to fix that unless your bios and your os support drives larger than 137gb. I hate to be the bearer of bad news, but they might only work as 137gb. Another thing that could fix the issue: a pci drive controller. What os did you put on it? XP? The first XP couldn't deal with drives larger than 137 without SP1. Do you have SP1 on it? Good luck.
