LDM – (ldm) Failed to start volume

This event indicates that the Logical Disk Manager could not start a volume because of configuration errors.

Cause

Possible causes include:

• The volumes in a mirror set are not synchronized.
• The volume is not fault tolerant, and a disk I/O error has occurred.
• The volume is fault tolerant and multiple disk I/O errors have occurred.
• A volume in the stripe set is missing.

Do one or more of the following:

• Check the status of your hardware for any failures (for example, a disk, controller card, or cable failure).
• Ensure all disks are present.
• Rescan disks to ensure that Plug and Play can detect all disks.
• Check if any disks have failed with bad sectors and need to be replaced.
• Contact Microsoft Customer Service and Support.
