Win2k3 Bad Free Disk Space Report

I have a windows 2003 R2 x64 4-way cluster that has a volume that is
incorrectly reporting the amount of free disk space.

The volume is 250 gb's. If you add up the folder sizes of the root
directories it equals ~60 gb's. However most every tool (explorer, fsrm,
etc) reports 234 gb's being used. The only tool I've found so far that
reports the correct amount of free space is disk defragrmenter.

It's not snapshots becuase those are only consume 2 gb's so that doesn't
even bring it close.

Google tells me all about how to fix this on a FAT32 volume on Windows 98.
Apparently this was a common issue back then.

Any ideas?

It's risky to claim that Windows incorrectly reports the
amount of free disk space. People would have found out
a long, long time ago! It is far more likely that you are
not fully aware of what's stored where. The following
command will give you accurate disk statistics:

fsutil volume diskfree C:

You can get fsutil.exe from here:

Use one of these tools to really see what's eating up your
disk space:

fsutil reports the free space correctly On a whim I removed the quota on
the drive and re-applied it and now quota manager (along with explorer, etc)
report the correct amount of free space.
