The NTFS error 'file system structure is corrupt and unusable' affects Windows 7 users who experience a complete lockup of their machine, requiring them to hold the power button to shut it down. The Event ID 55 error in the event logs indicates a potential disk failure, but fortunately, data can be safely backed up. This issue can be frustrating, especially when trying to diagnose and fix the problem.

To resolve this issue, we will explore two primary fix methods: using the built-in Windows utility 'chkdsk' and deleting the corrupted VSS folder from a Linux Live CD.

⚠️ Common Causes

  • The NTFS error 'file system structure is corrupt and unusable' can be caused by a corrupted file system structure on the disk. This can happen due to various reasons such as hardware failure, software corruption, or improper shutdown of the system. In this case, the Event ID 55 error suggests that the file system structure on the disk is indeed corrupt and unusable.
  • Alternatively, the issue may be caused by a corrupted VSS (Volume Shadow Copy Service) folder, which can occur when using backup software such as Crashplan.

🔧 Proven Troubleshooting Steps

Using the built-in Windows utility 'chkdsk'

  1. Step 1: Step 1: Open Command Prompt as an administrator and type 'chkdsk C:' (assuming the issue is on the C: drive) and press Enter. If prompted, confirm that you want to schedule the check for the next available I/O time. If the check fails, try running it again with the '/F' option (e.g., 'chkdsk C: /F').
  2. Step 2: Step 2: If the above steps do not resolve the issue, try running the utility with the '/R' option to recover any bad sectors on the disk (e.g., 'chkdsk C: /R'). Note that this may take some time and may require multiple attempts.
  3. Step 3: Step 3: After completing the chkdsk utility, restart your system and see if the issue persists. If it does, proceed with deleting the corrupted VSS folder.

Deleting the corrupted VSS folder from a Linux Live CD

  1. Step 1: Step 1: Insert a Linux Live CD (such as Ubuntu or Linux Mint) into your computer and boot from it. Once booted, open the terminal and type 'sudo chkdsk /F' to run the utility on the disk.
  2. Step 2: Step 2: Identify the VSS folder by running the command 'ls -l /dev/sda1' (assuming the issue is on the first hard drive). Look for a folder named 'vss_' or similar. Note down the exact path of this folder.
  3. Step 3: Step 3: Delete the corrupted VSS folder using the command 'sudo rm -rf '. Be cautious when deleting files, as this action is irreversible.

🎯 Final Words

If you have tried both methods and the issue persists, it may be a sign of an impending disk failure. In this case, replacing the drive with a new one is recommended to prevent data loss. However, if you are unable or unwilling to replace the drive immediately, you can continue to monitor the system for further issues and consider replacing it when necessary.
