I agree they should be SCSI and only presented that as a (possible) workaround and should have originally stated "possible". I also posted a reply suggesting that the disk be imaged to new SCSI virtual hard disks or the Disk DescriptorFile be edited.
@cdenesha With the imaging it can be directly from one disk to another (depending on how you want to go about it) or create an image file of the original and then write it to the new disk.
