Windows 10: freeing storage usage of windows storage spaces

Hi there,


I switched from winbtrfs to windows storage spaces. I have 4 drives for them and firstly attached 2 drives, copied data to it and then attached the other 2 drives and optimized the storage to equal the storage usage over the 4 drives. Unfortunately the blocks copied to the other drives were not freed on the drives instead the usage increased. Now my drives are full, but they are not really. I copied another 500GB of data and the usage was not increased. So this must be free sectors not used but marked as used.


My setup:




As you can see in the drive statistics I do not use that much storage:




Were are my lost 4TB and how can I get them back? I know from a friend who deleted files and there the storage usage decreased as one would expect.


What I tried:

- defrag/optimize the drive with windows defrag.exe and then another defrag tool to be sure

- Optimize-StoragePool -FriendlyName Speicherpool several times


Get-StoragePool gives:

FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly Size AllocatedSize

------------ ----------------- ------------ ------------ ---------- ---- -------------

Primordial OK Healthy True False 9.54 TB 8.64 TB

Speicherpool OK Healthy False False 8.64 TB 8.36 TB


What can I do further? May the refs be the problem here? If yes is there any way to convert to ntfs? Or any way to get the data to the other ntfs drive byte by byte without attaching another storage drive?


Any help would be much appreciated. Thanks!

:)

 

Storage Problem

Hi,

It's possible that the 346GB of space that you're seeing under the Apps & games window refers to the available space of the selected drive and not the actual usage. To confirm this information, we suggest that you check the total
usage through the Storage usage screen instead. To do this, follow the steps below:

• Click the Start menu or Windows icon.
• Select the gear icon or Settings.
• Select System > Storage.
• Under Choose a drive to see what's taking up space, select
  This PC (Drive letter)
• Under Apps & games, check if the space usage exceeds the estimate 140GB of space.

Let us know should you need further assistance.

 

Storage Space

Surface Pro 3 storage space is low. Storage settings say that Apps and Games is using 17.5 GB but when I add up the space from the list of apps it is only 5.7 GB. What is taking up up the other ~12 GB and how do I free up space?

 

Windows 10 - settings - storage usage - other?

Hi Steve,

It's possible that some folders are not showing under the Storage usage >
Others since they are hidden. Though they are hidden, the space that they are taking will still be counted under
Storage usage > Others. You'll have to identify what files and folder are hidden with the steps below:

• Type hidden in Cortana, the Windows search bar or your task bar.
• Select Show hidden files and folders from the result.
• Go to View tab.
• Enable the Show hidden files, folders, and drives.
• Hit Apply, then click OK.

Once you're done with these steps, try checking the Storage usage again and see if it will match.

Let us know if it addressed your concern.

Thank you.
