This is just a random pic of someone's settings off the net but it basically shows what I mean ...
I looks fine in the BIOS. Here's what is reported for the C: drive:
Device: Hard Drive
Vendor: WDC WD5000AAKS-00C8A0
Size: 500.1 GB
LBA mode: Supported
Block Mode: 16 Sectors
PIO Mode: 4
Async DMA: MultiWord DMA-2
Ultra DMA: Ultra DMA-5
SMART Monitoring: Supported

Thanks for the response.

I'd really rather not try that one unless I'm desperate. Thanks for the thought, though. I'll let you know if I decide to try this. It would probably take some time to stuff the drive, and then have to clean it out again.

If you are still experimenting you could try
(1) go to command prompt
>dir /a
and see if the free space agrees with windows explorer (probably will).
Means it's an issue you will have to resolve or your directory will think the disk is full when it isn't.
(2) depending on your comfort levels you could image c:
attach the vhd under disk management. Then see what windows explorer pie chart for the mounted image.

This may be a dumb troubleshooting question, but have you tried looking at a partitioning utility, and checking if there is unallocated space in D:? I don't know if that would show up in Disk Management or not, but it might be worth a try to boot into something like Gparted and examine D: outside of a Windows environment.

In computer management Disk management, if you right click on your drives (C or D) an option should appear for "expanding or shrinking" your drive space. Have you tried that?

There are times when Disk Mgmt is wrong, but normally Explorer won't agree.

However when Disk Mgmt is wrong on partitioning details or sizes, I use free Partition Wizard bootable CD (not the Windows version) to get the actual size or staus.

The size given for C is too close to what it should be for D to not think that they are being confused. However, to make sure i would also run chkdsk /r and the HD maker's diag/repair CD scan (Data Lifeguard) since the only way a truly 500gb HD would report such disparately less space is if it had multiple bad sectors quarantined by formatting.

Disk Check

You can run reasonably good versions of both of these tests from Partition Wizard CD: Check File System and Surface Scan. If they report errors I would cross-check with Disk Check and Maker's Diag scan.

By all means try anything but:
(1) Diskmanagement - cmd>diskpart commands confirm the disk/partition sizes. As does the BIOS.
(2) Windows Explorer - I Suggested cmd> dir /a . I expect the two to confirm.
If so there appears to be a disparity between the directory and the available disk space.

A disk check is always a good idea. I'd be tempted to schedule it directly from Windows though. See Tutorial. That many bad sectors would seem unlikely to me.

Then have a go at mounting an image as an option as I suggested earlier.

The only disk partitioning s/w I have is something like Partition Magic 7.01. I'll have to check to see if it works with large NTFS partitions and may give that a go.

A correction for your post: it's my C: drive that's not reporting correctly. D: reports correctly. For clarity, there are two physical drives, each with one partition using the entire drive. As you'll note from the Disk Management info (left hand screen shot on the initial post), the C: drive has no unpartitioned space. 465 GB is the correct reported size for a "500 GB" drive. Also, right clicking on the C: drive reveals only an option to shrink the volume, while extend volume is grayed out.
