    Hi! This seems a variant of a known CHKDSK error code, commonly indicating severe file system corruption or interference from third-party software.

    If the drive is still accessible, copy your important files off right away to another disk or cloud location before attempting repairs

    From an elevated Command Prompt, try simple checks first:

    • chkdsk E:
    • chkdsk E: /f
    • sfc /scannow

    Perform a full system scan with Windows Defender to rule out malware interference.

    If system corruption is the root cause, restoring Windows to a previous point or reinstalling may fix CHKDSK errors.
