Need more help with partitioning!

Hey guys,

So I've run some 3rd party defrag tool that sorted out the system files, and
now Vista's partition program says I can shrink my C: drive by 65GB, all the
free space on the drive.

However, when I try to shrink it by 20GB, it shows the following message:
"An unexpected error has occurred. Check the System Event Log for more
information on the error. Close the Disk Management console, then restart
Disk Management or restart the computer."

I've followed its advice but the problem still stands. I tried checking the
Event Viewer for more information, but it's very confusing stuff.

Help is greatly appreciated.
Cheers.

It may help you to shrink partitions by running the diskpart command from the
Vista DVD, which also avoids the occurrence of locked files.
