Windows Server 2025 local volumes must use a format that supports New Technology File System (NTFS) attributes.

The ability to set access permissions and auditing is critical to maintaining the security and proper access controls of a system. To support this, volumes must be formatted using a file system that supports NTFS attributes.

Open "Computer Management".

Select "Disk Management" under "Storage".

For each local volume, if the file system does not indicate "NTFS", this is a finding.

"ReFS" (Resilient File System) is also acceptable and would not be a finding.

"CSVFS" (Cluster Shared Volumes File Systems) is also acceptable and would not be a finding.

This does not apply to system partitions such the Recovery and EFI System Partition.

Format volumes to use NTFS, ReFS, or CSVFS.
