LDM – bad block(s) found

This event indicates that Logical Disk Manager has detected I/O failures on a disk. This error occurs when read and write operations fail.

Cause

Possible causes include:

• A hardware failure that prevents communication with a disk (for example, a loose cable, a loose disk controller card, or a cable failure).
• Uncorrectable bad sectors on a disk.

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).
• Check Event Viewer for additional events from lower-level storage drivers that might indicate the cause of the failure.
• Use Chkdsk or a similar software tool to check if any disks have bad sectors and need to be replaced.
• Restart the computer.
• Contact Microsoft Customer Service and Support.
