Deleting a locked partition table with Windows XP

Partition tables are lockable, for instance GUID Partition Tables (GPT) will do this, and even though you can see that the disk is attached and activated you may not be able to format it or see its contents. When using Windows XP, if you no longer need the data, the easiest way to get around this is to use the default installed tool DiskPart.exe to remove the disk's Master Boot Record(MBR).

From the XP desktop:
go to Start> Run...> cmd


Microsoft DiskPart version 5.1.3565 Copyright (C) 1999-2003 Microsoft Corporation.
On computer: Microsoft Windows XP [Version 5.1.2600]

DISKPART> list disk
