I have a Windows 2000 Server set up with RAID 5. I initially defined 2 136 GB logical disks 0 and 1. I have a small utility partition on disk 0 along with the C drive. I wish to extend the C drive to use disk 1 as well, which is now configured to drive D. I deleted drive D, but it is still in disk 1. I download partdisk.exe from MS, but am not sure how to accomplish what I want to do. I know I need to use extend, but I think I need to remove disk 1 and somehow add the unallocated space to disk zero, but am not at all confident on how to do it.
I found it very difficult to manage the disks in Windows XP / Server with the built in tool: Disk Management. I think you have to use a third party product / tool to do you job without loosing data. Check out this tutorial with some freeware: http://www.geeksdo.com/resize-server-partition-wizard-server.html (only for Servers)

You seems want to extend disk o partition with the unallocated space of disk 1, however you have not configured RAID configuration. And your disk 0 contains system partition. So that is a little diffecult. To extend system partition with the space of another disk is not realistic. In you situation you have to prepara a bigger disk and replace the system disk, you could choose migrate OS tool: migrate os to another bigger hard drive
Did you config the disk as hardware raid 5? However, from your description, it seems like you did not use the hardware raid 5. First raid5 need at least 3 disks, (there just two in your description, disk0 and disk 1) Second if you set raid 5 successfully, it will list as one disk in disk management (not two).
Therefore, you need to make sure your raid 5 is config in a right way. If you only have two disks I suggest you'd better set it as raid 0. BTW, if you want to resize partition on windows server OS, you could try Partition Assistant Lite which is a free partition software for Windows Server OS. Here is an article about how to resize partition on SERVER OS. Hope it could help you http://www.partition-magic.org/free-server/resize-server-partition-free.html
