How to fix ERROR_CAN_NOT_COMPLETE

Code:483 (0x1E3)
Teracopy: Reports error

Description

The request failed due to a fatal device hardware error.

Causes

This error indicates a serious hardware device failure, most commonly affecting storage devices like hard drives or SSDs. The device has encountered a critical failure preventing it from performing read or write operations:

  • Physical Damage: Storage device suffered physical harm from impacts, drops, or mechanical shock.
  • Manufacturing Defects: Inherent hardware flaws from the manufacturing process.
  • Overheating: Excessive heat causing component failure or thermal damage.
  • Wear and Tear: Component degradation from prolonged use, especially near end of lifespan.
  • Bad Sectors: Critical bad sectors on the disk preventing data access.
  • Firmware Corruption: Corrupted or malfunctioning device firmware.
  • Loose or Faulty Connections: Damaged cables, loose SATA/USB connections, or faulty ports.
  • Power Supply Issues: Inadequate or unstable power causing device malfunction.
  • Controller Failure: Hard drive or SSD controller has failed.

Solutions

Backup Data Immediately

If the device is still partially accessible, back up critical data as the first priority:

  • Copy all important files to another storage device immediately.
  • Use data recovery software if standard file copying fails.
  • Don't delay—hardware failures often worsen quickly.
  • Consider professional data recovery if data is critical and device fails completely.

Check Physical Connections

Verify all hardware connections are secure and undamaged:

  • Ensure SATA, IDE, or USB cables are firmly connected at both ends.
  • Inspect cables for visible damage, kinks, or wear.
  • Try different cables to rule out cable failure.
  • Test different ports (SATA ports, USB ports).
  • For external drives, ensure adequate power supply connection.
  • Check if the device is detected in BIOS/UEFI.

Run Disk Diagnostics

Use diagnostic tools to assess the device's condition:

CHKDSK (Windows Built-in):

  • Open Command Prompt as Administrator.
  • Run: chkdsk /f /r X: (replace X with the drive letter).
  • Allow the scan to complete—this may take several hours.
  • Schedule scan on next reboot if the drive is in use.

Manufacturer Diagnostic Tools:

  • Use tools like SeaTools (Seagate), Western Digital Dashboard, Samsung Magician, or Intel SSD Toolbox.
  • These provide detailed SMART data and comprehensive testing.
  • Follow manufacturer recommendations based on test results.

Check SMART Status

Review SMART (Self-Monitoring, Analysis and Reporting Technology) data:

  • Use tools like CrystalDiskInfo or Hard Disk Sentinel.
  • Check for warnings about reallocated sectors, pending sectors, or other critical attributes.
  • A failing SMART status indicates imminent drive failure.

Update Device Drivers

Ensure device drivers are current:

  • Open Device Manager (Win + X → Device Manager).
  • Expand "Disk drives" section.
  • Right-click the problematic device and select "Update driver".
  • Search automatically for updated drivers.
  • If issues persist, uninstall the device and restart to reinstall drivers.

Update Firmware

Check for firmware updates for the storage device:

  • Visit the device manufacturer's website.
  • Download the latest firmware for your specific model.
  • Warning: Follow firmware update instructions carefully—improper updates can brick the device.
  • Ensure stable power during firmware updates.

Test on Another Computer

Determine if the issue is with the device or the system:

  • Connect the device to another computer.
  • If the error persists on multiple systems, the device is likely failing.
  • If it works elsewhere, investigate the original system's hardware or configuration.

Disable Write Caching (Temporary)

For temporary access to retrieve data:

  • Open Device Manager.
  • Right-click the device under "Disk drives" and select Properties.
  • Go to the Policies tab.
  • Uncheck "Enable write caching on the device".
  • This may allow limited access to retrieve critical files.

Check for Overheating

Ensure adequate cooling:

  • Check if the device is excessively hot.
  • Improve case ventilation and airflow.
  • Clean dust from cooling fans and vents.
  • Use monitoring software to check drive temperatures.
  • For external drives, ensure they're in a well-ventilated area.

Consider Professional Data Recovery

If data is critical and the device has failed:

  • Stop using the device immediately to prevent further damage.
  • Consult professional data recovery services.
  • Don't attempt DIY repairs on physically damaged drives.
  • Recovery services can often retrieve data from failed drives.

Replace the Device

If the hardware is failing:

  • Fatal hardware errors often indicate imminent complete failure.
  • Replace the device before total failure occurs.
  • Check warranty status—many drives have 3-5 year warranties.
  • Consider upgrading to more reliable storage (e.g., quality SSD).

Preventive Measures

To prevent future occurrences:

  • Regular Backups: Maintain automated, regular backups of critical data.
  • Monitor Health: Use SMART monitoring tools to track drive health.
  • Proper Handling: Avoid physical shocks, especially for mechanical drives.
  • Temperature Control: Ensure adequate cooling for storage devices.
  • Quality Hardware: Invest in reliable storage devices from reputable manufacturers.
  • UPS Protection: Use uninterruptible power supplies to prevent power-related damage.
