Some very nice new features in the latest update to converter. One that I am very happy about is the ability to split a single disk into multiple VMDK files. For example if a physical server has one 72 GB drive that has a 20 GB C drive and a 45 GB D drive. In the previous version a single VMDK with two partitions would have been created. This was a pain because it made it difficult to extend a volume. Now there is a new check box in the disk selection screen that lets you split those two partitions into two separate VMDK files.
