vSphere convert VM IDE disk to SCSI disk

I recently read a post by Duncan Epping over at Yellow Bricks where he tried to resize the VMDK of a Windows XP VM running on ESX\vSphere. When he used the VI Client to try and resize the VMDK he was actually unable to because it was ghosted out. By coincidence I had experienced the same problem a week before Duncan after building 5 Windows XP VMs for stress testing of a new SharePoint website. As Duncan mentioned, the only other time I had seen this happen was when a snapshot existed for the disk that needed to be resized. Quickly checking the VM's settings I noticed that by default, when you create a Virtual Machine using the 'Microsoft Windows XP Professional..." Guest Operating System container it actually attaches an IDE disk rather than a SCSI disk (Server 2003 and 2008 Guest Operating System containers use a SCSI disk by default.)
