I have 2 Boot RAM Disks (5 GB each) on my system.
Disk Z: ephemeral, for system and user TEMP/TMP directories. exFAT formatted (cluster: 32KB).
Disk Y: backed by an Image, for some apps cache redirected to RAM disk by symbolic directory links (some by SoftPerfect Cache Relocator 1.6, and some manually). NTFS formatted (cluster: 4KB / compressed volume). Contents of this RAM disk saved to image every 5 minutes. Disk image is located on dedicated volume (NTFS / 4KB / not compressed) on NVMe SSD (there is no underlying issues with SSD).
I regularly have following issue with second (Y) RAM disk:
From Windows Event Log (two following events):
Level: Warning / Event ID: 98 / Source: NTFS (Microsoft-Windows-Ntfs)
Volume Y: (\Device\HarddiskVolume25) requires an Online Scan. An Online Scan will automatically run as part of the next scheduled maintenance task.
Level: Error / Event ID: 55 / Source: NTFS (Ntfs)
A corruption was discovered in the file system structure on volume Y:.
The exact nature of the corruption is unknown. The file system structures need to be scanned online.
When scanning with chkdsk, I get such errors:
File record segment X is an orphan.
chkdsk Y: /Fsolves this problem easily. But judging by Windows Event Log, this problem occurs on average every 3-7 days, but there are cases of occurrence an hour after the problem is fixed.
It is difficult for me to judge when this type of problem began to reveal itself, since I didn't notice any actual problems with applications that work with this RAM disk. And I discovered this problem only when I scanned all disks in my system.
Subjectively, I began to notice problems in the first half or middle of last year. Possibly after upgrading to version 4.2 which was released on 2021.01.04. Now I use SoftPerfect RAM Disk v4.3.1 x64 and the problem continues to arise.
Apps that actually R/W on this RAM disk:
Pale Moon (cache)
qBittorrent (.fastresume files and logs only)
GOG Galaxy Client (cache and logs / no games)
Thus, there is no significant write/read load on this RAM disk.
Please help in identifying the source of this problem. Any suggestions how to trace such problem on OS or application driver level?
OS: Windows 10 x64 v1809

Storage (OS and RAM Disk Image volumes): Samsung SSD 960 PRO 512GB (NVMe 1.2 / No SMART Errors / Percentage Used: 24% / Available Spare: 100%)
