I tried to expand my virtual hard disk in VMWare Fusion (6.0.4) for my Windows 8.1 guest. In the end VMWare showed me an error message that my attempt failed. Nevertheless it perfectly shows the correct new size under hard disk settings, so does the Windows Disk Management under Disk 0 under C:\. My problem: I can only effectively use the original space and everything else in Windows still shows me the original size. I don't have any unallocated space. What's going on here? Any solution?
