File Replication Service is a multiple-master replication, multithreaded engine included in Microsoft Windows Server versions. Abbreviated as FRS, this service is used by Windows 2000 server to replicate logon scripts and system policies for Windows 2000 based and other servers. When FRS performs any I/O operation on the disk, it maintains the data in cache in order to increase the performance. If operated on an NTFS volume, this cached FRS data might get lost under highly stressed conditions, which might leave the disk in inconsistent state. One of the solutions to resolve disk inconsistency is to reformat the disk. If you do so, you lose all the data that is stored on the disk. To recover this data, use your recent backup or if no valid backup is available, scan the disk using a powerful third-party Data Recovery utility.

To illustrate this, consider that FRS performs an I/O operation on a Windows 2000 based system. If the I/O is stressful and is being performed on a volume that is formatted to NTFS file system, you might come across the below error message:

“Event ID 41.
The file system structure on the disk is corrupt and unusable. Please run the Chkdsk utility on the volume "Name.”

Further, when you run Chkdsk to check the consistency of the disk, you receive one of the below error messages:

“Deleting corrupt attribute record (16, "") from file record segment xxx.”

Or

“Correcting error in index $30 for file 100”

Windows 2000 system error log records this entry for dirty volume with event ID 55.

Cause

A Windows 2000 based system exhibits the above discussed behavior if some of the cached has not been successfully written to the disk. This particularly occurs under stressful I/O operations. This leaves the disk in corrupt state.

Solution

You are suggested to install the latest updates available for your operating system. However, to solve disk inconsistency, you need to reformat the disk and use your backup to restore data thus lost.

At times, backup fails to give the desired results. In such cases, you are recommended to use hard drive recovery software to extract the lost data. Data Recovery applications are highly influential and powerful utilities designed to perform safe data recovery using suitable scanning algorithms. These applications serve as valid Partition Recovery tools as well.
