Diagnosing that problem, specifically, is probably off topic, but I can assure you that the tools on Windows 7 can expand an active file system. I shrank and expanded a partition (the C:\ volume) on Windows 7 Home Basic this morning, and I'm absolutely certain that every version of Windows 7 (and Windows Server 2008) can resize an active NTFS volume, with no chkdsk required.
