Is there a method/utility to actively resize the partitions on a dual-boot macbook air, without destroying the contents? I made the Windows Partition too small initially, and all the places I've looked have stated that resizing now using bootcamp will destroy all data on the Win7 Partition. I would prefer free, but I'm open to a reasonably priced utility that can grow the Win7 partition into the available space (I can use bootcamp to shrink the OSX partition without any problems).
