I'm running Vista on an Asus laptop, with a 120GB SATA primary hard drive. A few months ago, I used Computer Management<Storage<Disk Management to partition this drive in two. Shortly afterwards, I reduced the size of the second partition on two separate occasions. At present, Disk Management lists the various partitions as follows (in order):
VistaOS (C: )
62.13 GB NTFS
Healthy (System, Boot,...)
Recording (D: )
14.70 GB NTFS
Healthy (Primary Partition)
Unfortunately, I have almost filled up my C: partition, and I want to use the unallocated disk space to extend it. However, when I right-click the partition in Disk Management, the "Extend Volume" option is grayed out. I have also tried to use diskpart.exe to extend the partition manually, but this claims that my hard disk doesn't have even 1 MB free (which is clearly false, since when I ask diskpart to "list disk", it tells me that my hard drive has 32 GB free, as expected).
How do I get around this? Any help will be greatly appreciated.
