Microsoft Windows 2000 Advanced Server and Datacenter Server operating systems support relatively advanced clustering service, when compared to its earlier Windows versions supporting the same service. Using cluster service allows you to connect to multiple servers that are a part of server clusters and hence you can easily manage the data and programs operating within the particular cluster. In such clusters, the individual computers are termed as nodes. Resources of these clusters could be physical components like hard disk, network cards etc. and also the logical components like applications, databases etc. At times, you observe file system corruption on shared cluster disk, specifically when the disk contains a non-NTFS partition. This might lead you to delete such partitions and restore lost data from backup. However, the unavailability of valid data backup calls for using powerful data recovery applications.

  You might receive the below error messages with your Windows 2000 (Advanced Server and Datacenter center editions) system that is configured to use Windows Cluster service:

  “The file or directory X:\$Mft is corrupt and unreadable. Please run the Chkdsk utility”

  Alternatively, you might encounter the similar error with event ID 26:

  “System Process - Lost Delayed-Write Data”

  Cause

  Above stated errors signify file system corruption. This occurs when the cluster disk is online on a single cluster node and at the same time, other nodes access the same disk. Shared cluster disk could get corrupted in such situations if contains a non-NTFS hard disk partition.   Solution

  Consider these steps to resolve the above issue:

  The latest service pack of Windows 2000 has a fix of this problem You can identify a NTFS partition by ID 0x07. You can use Diskmap tool to determine the exact IDs of your disk partitions. If it is other than ID 0x07, you should delete that partition and restore lost data from backup. However, to fix disk corruption, you should run chkdsk or reformat the disk as the last resort.

  If backup seems to exist in invalid state or you don’t have any backup, use disk recovery applications to locate and restore the missing information. Such tools prove effective Data Recovery utilities to recover lost files, folders and partitions.
