Firstly here's a rundown of the hardware and software:
MS Windows 2003 Enterprise R2 SP2 on a HP DL380G3
connected to an MSA60 Storage Enclosure
5 x 750gb SATA HDD
RAID 5 - 2.8TB

Basically i need to convert the new basic disk to GPT as it is over 2TB but when i right-click on the disk in Disk Management the option 'Convert to GPT Disk' is greyed out

The command line util Diskpart is also unavailable - when i run it from the command promt i get the following error:
Microsoft DiskPart version 5.2.3790.3959
Copyright (C) 1999-2001 Microsoft Corporation.
On computer: XXXXXXXX

The disk management services could not complete the operation.

Any ideas or help would be greatly appreciated

Is there any partition on this HDD? Is it basic or dynamic?

It's a basic disk and there are no partitions on it, 2.8TB of unallocated space

Try to Initialize the new disk later by using the Initialize Disk option in the Disk Management console.
There are rules for adding new drives:
After installing a new raw disk, open the Disk Management console to launch a wizard that you can use to configure the new disk. The wizard includes options to initialize the disk as MBR or GPT.

I have tried that but there is no option to initialize as MBR or GPT - it initilizes as MBR by default and then gives the option to conver to Dynamic only

erm, is there cluster configuration based on your server? I see the only reason why you cannot change it to GPT - cluster.
Have a look on this article of Microsoft: http://support.microsoft.com/kb/919117

yeah, was going to suggest this. Is there any Non common configuration where your server takes part?
