Hello, this is my first first, and I've been having this problem for awhile now. My hard drive is showing a capacity of 186 GB when it's supposed to be 200 GB. Based on what's installed, it's currently at 164 GB. I've used Grand Perspective, WhatSize, Main Menu, and Disk Inventory X to try and help the issue, but nothing works. If anyone has a suggestion that may help me out, I would appreciate it. I've seen that several people have had a similar problem, and so far none of the suggestions made worked. P.S. Repair disk shows that there isn't any issues.
