Error Message
V-76-58645-828 - Extend operation did not complete because cluster count is higher than expected
Cause
The issue can occur when there is an attempt to expand the volume over the cluster size
The fsutil command line utility can be used to determine the current cluster size

Please see the following Microsoft article https://learn.microsoft.com/en-us/windows-server/storage/file-server/ntfs-overview to determine the appropriate cluster size
Resolution
The existing cluster size cannot be modified once the volume is created.
1) To address this issue, create a new volume using an appropriate cluster size for the volume size.
2) Then backup the original volume and restore to the newly created volume.
