Windows 10: Windows storage spaces data missing for no reason

I've been using my Windows storage space for a year or so with no problems at all, but recently I've noticed folders and files are disappearing. Currently running build 19042.985 Checked all of the storage space info, all 4 drives are still are still marked as OK, and it shows the correct pool size and used space. However, when I right click on the properties of the storage space in Windows Explorer, it only says that 2.76 TB are used, when 4.30 TB are used. Additionally, I am unable to see around 600gb of files that I've been looking for, and there is no sign of physical issues with the drives. I've used both chkdsk /f and SFC which return no errors, so I'm becoming very confused. Hoping to find some answers, most of the data is safe already but I'm wanting to try to rebuild what I have here. Thanks!

Windows storage spaces data missing for no reason

Hi, given the anomalies, whilst you say there's no physical damage- I assume you've run some kind of disk check- I suggest you get a copy of Hard Disk Sentinel (SSDs too) - trial- and run that. Best instant appraisal right on its GUI I know of.

Click the tab for each disk to see the report.

Any way to downgrade ver. of MS Storage spaces volume w/o data loss?

1. Install Windows 1607 & 1709 dual boot system
2. Connect two free disks
3. Boot into 1607
4. Create storage pool, assign two free disks, create two-way mirror volume
5. Copy data to new volume
6. Reboot into 1709
7. Upgrade your Storage Space pool to gain new features as MS suggests
8. Reboot into 1607
9. Your Storage Space configuration looks now as in the picture, volume is inaccessible
10. Notice that doing step 7 was not the smartest idea, data are now accessible only from Windows 1709.

Question: Is it possible to simply revert Storage Spaces metadata back to version 1607? Answer: No. It is necessary to backup data, destroy upgraded pool, create new pool & mirror in Windows 1607, and restore data.

Is it so hard to understand what necros asks for?
