Missing 103GB of disk space

I have two SATA drives C=232GB and D=698GB

On C if I select all files/folders and look at properties (or use
JDiskReport) the amount of disk space nearly matches the pie chart on
the drive properties.

If I do the same on D there is a difference of 103GB, the pie chart says
I'm using more than I actually am.

I have not got shadow or System restore set on drive D.

I unhid ALL files from folder tools. I have done a CHKDSK and no free
space was released.

Any clues to where my 103GB is?

I noticed during a defrag with diskeeper (11.0.706.0) that the free
space was shrinking whilst the defrag was in operation.

Do I have to reformat the drive to get the space back?

One explanation would be that your HDD has developed bad sectors, these
would be marked as unusable after running chkdsk, but you say scandisk
didn't report any errors ?.
I would run the HDD manufacturer's diagnostic tools first, if still no
errors then formatting would be an option.

I think there is a problem with Volume Shadow Copy as this is what keeps
popping up when I try Google.

Apparently when you defrag the HDD it can case shadow copies of each
file to be produced. Though I have system restore switched off for this
drive.

I'm going to switch off system restore and reboot and do a disk tidy to
see if that recovers any space. I'm currently backing up the data on the
drive and it takes for ever as my backup drives are USB

If the Disk tidy fails then I'll have to try a reformat.

Just a thought have you tried looking in Disk Management under
Administrative Tools>Computer Management and looked to see if you have an
unallocated space?

The disk was fully formatted with only one partition. Also it was
working properly with XP, 3 weeks ago.

I have now reformatted as disk tidy did not cure the problem.

I've formatted with 32K cluster size as 16K and below are said to cause
a problem with VSC and defrag. The drive has mainly very large files on
it so the cluster size will not waste too much space.

Since reformatting the HDD the used space now reports the same in
properties as JDiskReport give or take a few MB.
