Disk Manager and Properties size doesn't match that of TreeSize

[Scott Simpson]

I have a disk that has a 69.66 gig partition according to the Disk Manager.
If I select Properties on the drive, it shows 62.1 gig used and 7.49 gig
free. However, if I run TreeSize or DiskDetective, they only show about 32
gig used. Where is half my space? I can't find it. Thanks.

 

[Andrew E.]

Try run,type:cmd In cmd typeiskPart In DiskPart type:list disk
type:list volume The results will show where the space is,or isnt.

There are some files which mess up reconciliing used space + free space
= disk size.

Go to Start, Control Panel, Folder Options, View, Advanced Settings and
verify that the box before "Show hidden files and folders" is checked
and "Hide protected operating system files " is unchecked. You may need
to scroll down to see the second item. You should also make certain that
the box before "Hide extensions for known file types" is not checked.
Next in Windows Explorer make sure View, Details is selected and then
select View, Choose Details and check before Name, Type, Total Size, and
Free Space.

You will find some files remain hidden even after taking the action
referred to above. Notably the contents of the System Volume Information
folder, where System Restore points amongst other things. The default is
12% of the drive which for your drive equates to about 4.58 gb.

Are you using Norton Protected Storage?

Are you using any utilities e.g. Norton Ghost to back up or image files
on your drive?

Do you use the Hibernation feature? How large is hiberfil.sys. This is a
hidden file like the contents of the System Volume Information folder.
It needs to go into your reconcilation.

That isn't it. hiberfil.sys is 1.03 gig and pagefile.sys is only 1.56 gig so
I'm still short about 30 gig of space. WinDirStat shows only 27.8 gig used on
a 70 gig partition yet the Properties of drive C: says I only have 7 gig
free. This still leaves about 30 to 40 gig missing.

Also, note that WinDirStat shows hiberfil.sys and pagefile.sys in its map so
those file are included by WinDirStat.

This is a Lenovo laptop running Lenovo Rescue and Recovery but that is in
another partition and shouldn't any effect.

Perhaps another slice of an NTFS file is being used when isn't showing up in
WinDirStat (or TreeSize)?

 

[Scott Simpson]

One other thing. WinDirStat shows the partition as 35.3 GB but Properties in
Windows Explorer shows it as 69.6 gig. Why the difference?

What is the disk size in Disk Management? Start, Control Panel,
Administrative Tools, Computer Management, Disk Management.

What are you using to backup data etc?

Disk management also shows 69.6 gig. I can't figure out why all the disk
space tools show about 32 gig and the partition tools show 69.6 gig. Perhaps
one or more NTFS files are using other slices than the primary one and that
is the reason? I can't imagine why that would be the case.

Open Disk Defragmenter and click on Analyse. Select View Report and
click on Save As and Save. Now find VolumeC.txt in your My Documents
Folder and post a copy. Do this before running Disk Defragmenter as it
is more informative.

I have DiskKeeper installed on the laptop (it came with the laptop).
Diskkeeper says the C: drive is 71.3 gig and reports

Findings on C:

Diskeeper has completed analysis of this volume and found 508 fragmented
files and/or directories and 4710 excess fragments.

The average number of fragments per file is 1.01.

On average, you have 1% excess fragments per file on this volume, with 11%
of the total volume space available for defragmentation. This amount of free
space is sufficient for effective defragmentation at this time, but as the
volume fills up, lack of free space will cause a performance problem. You
might consider which files you could delete or move to another volume to
maintain enough free space to keep the fragmentation level low. You should
use the Smart Scheduling option in Diskeeper to automatically keep
fragmentation at a low level. Click the Set It and Forget It tab in the
Diskeeper display to set up a Smart Schedule, or to confirm whether any
schedules are set.

I don't know of a way to run the regular Windows defrag with Diskkeeper
installed unfortunately.

Hope this helps.

OK. I figured out how to get a report using Diskkeeper. Report is enclosed.

This Report discloses another series of files, which I suspect are not
taken into account in your disk space calculations. An example is:
