Event 55 System Structure Corrupt

less than 1 minute read


Windows 7 system logs started recording event ID 55 (NTFS) => The system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume DeviceHarddiskVolume2.


To Resolve:

  1. Download WinObj utility from Windows Sysinternals or if you use WSCC like me then just use it.

  2. Launch Winobj.exe and go to GLOBAL section.

  3. Sort entries by SimLink, find a device corresponding to the one in your syslog error and check name column for drive letters.

  4. If it is the system drive (C: in most cases), then you will need to schedule CHKDSK to run on next startup. From elevated command prompt, run chkdsk /f c: and then type y to schedule on the next restart.
