diskpart wont let me extend... Whats up?

The Disk is Dymanic as it was Mirrored. We broke the Mirror, then went to
extend it.
Here is the Diskpart info...

Microsoft DiskPart version 5.2.3790.1830

DISK - Print a list of volumes on the disk.
PARTITION - Shows details about the current partition.
VOLUME - Print a list of disks that contribute to the volume.

Hello Scott,

Thank you for using newsgroup!

From your post, I'd like to provide you with the following information for
your reference:

2003, in Windows XP, and in Windows 2000

RE:"System or boot volumes may be blocked from being extended"

Would it not have been easier to say that I cannot extend my System Volume?
> | * Volume 2 C NTFS Simple 10 GB Healthy
> System

What is with the 'may be' are there instances where you can Extend the
System Volume?

So what about Extending the Broken Mirror Drive? Its not marked as System..

When I try to Extend, it says it was Successful, Though does not report that
its been Expanded. A Reboot later its still the original size.
