FILESYS-X-189: Error writing FAT table for volume server\volume.
Source: FILESYS.NLM
Explanation: A write error has prevented the operating system from recording changes made to the File Allocation Table (FAT). The FAT tracks what disk blocks are allocated and free; it also records what disk blocks are grouped together to store a file's data. The server will still have the correct FAT information in memory, and it still can access the volume correctly. However, when you try to mount this volume the next time, the FAT information on disk will be incorrect, and the volume probably will not mount.
Possible Cause: A hard disk or channel failure occurred. The disk could have other data integrity problems.
Action: See "Disk Errors in the Server Operating System Administration Guide.
