Missing HDD Space

OK, so I installed Vista Ultimate x64 on the puter into a 100GB partition on a 1500GB (1.5 TB) Seagate 7200.11. After install I used the install CD and command prompt with diskpart to extend the partition over the entire 1500GB. Yea, that resulted in the following screenshot.



As you can see, the bottom part of disk management shows the full 1.5TB of drive capacity, but the top screen only shows 100GB. What gives?!

System Specs:
ASUS P5N-D
Intel Core 2 Duo 6320 @ 1.86 GHz
4GB OCZ PC2 6400 DDR2 MEM (2x @GB)
1.5TB Seagate
500GB Seagate
XFX Nvidia 8800GS
Windows Vista Ultimate x64

Anybody? Do you need more info?

Evidently some error occured. I would reboot into the Partitioner and recheck it. perhaps resize it again to the 100GB that it reports, then restart, and use disk Management to Extend it.

Next time you want to extend the volume size, simply right click the volume, and click "Extend" in disk management

try this:
Paragon Partitioner
