Why Consider this
Event ID 55 is reported if the operating system detects the file system structure on the disk is corrupt and unusable. This is typically related to a failure condition with the disk subsystem and may stop the machine from functioning correctly.

Context & Best Practices
The file system structure on the volume listed in the message might be corrupt because of one or more of the following reasons:
- The disk might have bad sectors.
- I/O requests issued by the file system to the disk subsystem might not have been completed successfully.
If there is any indication of a structural problem, replace the disk as soon as possible. In case of SAN connections (LUN), investigate access to the SAN.
Suggested Actions
Check the state of the file system and repair it if necessary.
How to Troubleshoot
- Select Start, select Run, type cmd and then press Enter
- At the command prompt, type:
- chkdsk /X Drive:
Chkdsk runs and automatically repairs the volume.
- chkdsk /X Drive:
If the following message appears, type Yand then pressEnter.
“Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts?”
The next time the computer is started, Chkdsk will automatically run.
