Virtual Server: Cannot add a large disk

When adding a 135GB virtual disk to a VM I get this error:

"The hard drive settings could not be saved. The virtual hard disk image “f:\VM DISKS\data3.vhd” is too large for the IDE bus. Make sure that all virtual hard disk images connected to the IDE bus are not greater than 127 GB."

Can it really be true that the maximum disk that can be added to a VM is 127GB??!!

I am trying to do a Disaster Recovery Test for a client’s server with a 135.59GB C: (system) partition on an HP SCSI RAID array.
I cant find anything else about this in Google.

I'm Running Server 2003 Enterprise with Virtual Server 2005 R2 in case that’s relevant.
All help gratefully received.

Arnt you able to select SCSI int typed hard drive in VM? (i should ask what type of VM you use, is it truely the Virtual Machine from VMware or the Virtual Machine from Virtual PC (microsoft) or any other virtualisation tool?)

I know VMware supports the selection of SCSI type disks...

You have to add a virtual SCSI device.
Then you get the option to attach a virtual disk to the SCSI bus
This in turn allows a large system partition
Many thanks
