I just used Acronis to increase the size of my HD in my laptop from 250 GB to 320 GB. The upgrade was successful but my computer shows the HD as still being 250 GB. There is approximately 65 GB of unallocated space. My OS is Vista. I have recovered unallocated space with Disk Director ("DD") on XP machines. Disk Director allowed me to recover unallocated space from the same drive letter in XP. In the latest DD build, it does not allow me to recover the unallocated space. I want to recover the 65 GB of unallocated space and increase the size of Hard Drive (C. Can someone please tell me how to do this? I tried right clicking on the unallocated space and selected "create partion", but got a message that this operation failed. I also tried to create a partition hoping that DD would give me the option of selecting the unallocated space but got the last error message.
