In Windows 2000, physical disk resource is the cluster-capable disk that is managed by physical disk resource type (the shared disk connected to one or more nodes in a cluster) as a cluster resource. These physical disk resources cannot be created for logical drives or partitions but instead as entire physical drives. But at times, you run into an issue while attempting to bring a physical disk resource to an online state. It is possible that your hard disk file system is corrupt and you need to reformat the hard drive. In such situations, you need to use a recent and valid data backup to restore the lost information. But if data backup is invalid, insufficient or non-existent, data recovery applications should be used to extract the lost data.

Consider an instance, you attempt to bring physical disk resource to online state and observe one of these issues:

• You receive an Event ID 1066 in the System Log of Event Viewer with the following description:

"Cluster resource Disk Y: is corrupt. Run chkdsk /f to repair problems."

• Resource fails to come to online state and takes longer time than expected
• Chkdsk/f runs on shared hard disk

These issues are specific to Windows 2000 Advanced Server and Datacenter Server editions.

Cause

Possible causes of above issues are:

• File system corruption
• Permission issues

Windows cluster service performs a series of steps to determine the possible corruption in disk resource and if this operation fails, it runs Chkdsk/f to repair the possible file system issues.

Solution

To correct this problem, you need to carry out these methods:

• You should run ChkNTFS to determine the state of dirty bit.
• If the bit is not reported as dirty, you need to troubleshoot permission issues.
• If the bit is reported as dirty, you need to run Chkdsk/f command on shared cluster disk. However, if Chkdsk fails to correct disk corruption, you should reformat the hard drive and restore lost data from backup. But if the data backup is not up-to-date or in an invalid state, Data Recovery Software tools can serve the purpose of salvaging lost data. These are advanced Data Recovery applications that use powerful scanning algorithms to extract lost data.
