Ten thousand or more corruptions were detected on this volume and it was disabled from further optimization. A large number of file access failures is expected.
Corruptions can occur due to a variety of hardware or software errors which lead saved data to silently change.
Check the Scrubbing log in the Event Viewer under Microsoft->Windows->Deduplication and run Scrubbing in -full and optionally in -readonly mode using the Start-DedupJob powershell cmdlet. Run chkdsk on the volume to scan and report any file system issues. Restore corrupted files from backup and consider checking and replacing the disk drives hosting the volume.
