I have a Compaq Prolient windows 2000 server.
3 X 18.2GB hard disks running Raid 5
I have created 3 primary NTFS partitions configured as follows: C: 4GB E:5GB F:5GB
I have 20 GB unpartitioned space.
My question is why can I not create a partition out of the 20GB free space.

The complete capacity of all the disks should be 54.6GB. In disk management I only see around 35GB I assumed that the missing amount would be for Raid 5. I have only managed to partition around 15GB

RAID 5 Overhead doesn't account for the lost space (n-1) (18.2+18.2+18.2)-18.2= 36.4GB of usable space.

You will need to backup your data and delete the (2)PRIMARY 5GB partitions, then create an Extended partition and slice that up into your 5GB + 5GB + 20GB partitions.

One important thing that you did not mention was that if you were running a hardware RAID or software raid. That can make difference between what you have to do with the extra space. If it is HW, then go into the RAID controller and fix it there.If it is SW RAID, then W2K has to be dynamic, and the rest is easy.
