Around 100GB of HDD space missing?

Nesh

Double Agent

I have a second HDD in my PC for saving file and such and all of a sudden around 100GB are missing.

This is a D drive. It says that 324GB are taken. I select all items in the HDD it says 222GB,
I run a Disk analysis using WinDirStat still 222GB.

I have no idea where the rest is. There are no restoration points on the disk as far as I have checked.
This is a brand new drive, and the Crystal Disk Info shows that the health of the drive is Good.

Did the system place a swapfile/pagefile on it? Or the hibernatefile? I'd check for hidden files in the root, but i thought WinDirStat would show those already.

It shows only the pagefile which I moved away from the C drive and placed it in D. It takes only 2 GB.
It keeps shrinking every few minutes.
I ve never seen anything like it.
 
I could maybe understand if the space was being used up by something like an index file or thumbnails, but to not have the space accounted for is baffling. I could also understand if it was difference between Size on Disk versus Actual Size, but there wouldn't be missing space.

Best of luck on completing this adventure!
 
Have you restarted? Is something copying/moving to the drive but you don't have a disposable for it?

You should be able to see which folder is expanding?

I restarted and nothing. It doesnt show any difference in the size of folders other than the fact that the drive's free space gets smaller and smaller. Restarting doesnt free space. The total free space is just shrinking. The size of everything visible in the HDD retains the same allocation of space. Its as if something invisible is taking space. And it is not the pagefile
 
So the Used space stays the same, the total capacity stays the same, but your free space is shrinking?
 
Btw I am not sure if its related but this phenomenon appeared right after my Windows 10 updated. Of course none of the update files reside in the D drive.

I am currently formatting the drive out of curiosity.

What does the windows resource monitor thingy say? Check disk I/O tab, see if you can nail down the culprit.

Some months back there was noise about Spotify spazzing out and eating major disk space, to the point of potentially wearing out SSDs if left unchecked for extended periods of time.

I don't suppose you have a now ancient version of Spotify installed/running? :p

No Spotify here. I couldnt even find anything strange in the Processes of the Task Bar. I didnt think about checking the disk I/O tab though

I formatted the drive and I am now waiting to see if it will repeat the same thing. My D drive is an HDD.

Try running check disk fix mode on it

Try scanning it with diskusage app https://foldersize.codeplex.com
I tried to check the disk for errors. No errors present.

I think the app you suggested does the exact same work as WinDirStat

Are you using the drive for Windows Image Backups? If so, click on the folder, and as Windows keeps asking for permission to open them, grant it. Do that for every folder and then you can see how much drive space all the files are taking up. If you don't do that Windows shows nothing for the size of the backup folder. If you have no such backup folder, still try the above for every folder to make sure Windows is showing their size.

I havent set up the drive for image back ups.
Maybe it did it automatically after the Windows 10 updates? If not, I dont think there is a back up folder.

I am a bit confused. I thought the above were specifically referring to a back up folder so I am not exactly sure what I should try.
I think I am missing something

Dunno about that app but in foldersize, it should include hidden and system files.

Maybe running it as admin?

Also check the hdd block with partitioning/disk repair tool. Maybe it goes bad sector?
 
Tried running the built-in disk cleanup utility on the drive? It has a system files mode too.
