Windows Error 1184: “An Attempt Was Made to Access a Partition That Has Begun Termination”

Why This Error Happens

Error 1184 occurs when a process or service attempts to read from or write to a system partition (often related to Kernel Transaction Manager or a volume) that Windows has already marked for teardown or dismounting. This typically happens due to an improperly terminated application, a corrupted volume shadow copy, or a driver that fails to release a handle before the OS proceeds with partition cleanup. It can also surface when NTFS transactional resources are left in an inconsistent state after a crash or forced shutdown.

Step-by-Step Resolution Guide

  1. Check Disk for Corruption
    Open Command Prompt as Administrator (Win + X → Terminal (Admin)) and run:
   chkdsk C: /f /r

Schedule the check on next restart if prompted, then reboot.

  1. Verify Volume Shadow Copy Service (VSS) Integrity
    Run the following to check for VSS errors, as they frequently interact with partition termination states:
   vssadmin list writers

If any writer shows “Retryable error” or “Failed,” restart the associated service via services.msc, or reboot the machine.

  1. Update Storage and Chipset Drivers
    Go to Settings → Windows Update → Advanced Options → Optional Updates → Driver Updates. Install any pending storage controller (AHCI/NVMe/RAID) or chipset driver updates, as outdated drivers can mishandle partition dismount signals.

  2. Check Event Viewer for the Triggering Process
    Open eventvwr.msc → Windows Logs → System. Filter for Event ID 1184 and note the source application/service in the event details. If it’s tied to a specific third-party backup or disk management tool, update or reinstall that software.

  3. Repair System Files
    Run the following in an elevated Command Prompt to fix underlying corruption that may be causing improper partition state transitions:

   sfc /scannow
   DISM /Online /Cleanup-Image /RestoreHealth

Restart once complete.

Alternative or Verification Steps

  • Verify the fix: Reproduce the original action (e.g., the backup job, disk operation, or app launch) that triggered the error and confirm Event Viewer shows no new Event ID 1184 entries.
  • Alternative fix: If the error persists and is tied to a specific disk, disconnect and reconnect the drive (for external disks) or, for internal drives, use Disk Management (diskmgmt.msc) to manually verify the partition is online and not stuck in a “pending” or “offline” state before retrying the operation.
