On a HP Proliant Server I added a 36GB drive to the Raid 5 array. I did this using the HP Array Configuration Utility. When the process had finished (after many days) I went to the disk management in Windows 2003 Server and saw that there was 36 GB of unallocated space. I then installed diskpart for Windows 2003 Server and ran it to extend the volume. I only have one volume (c:). The diskpart process completed sucessfully.
However, I go into disk management now and the lower section shows the full volume size of 140GB, but the upper section (and in My Computer) shows 104GB.
I have tried rescanning the controller, updating drivers, etc. I need to correct this problem.
