How to Recover Data From a Failed External Hard Drive
Hard drive failures are not entirely uncommon, owing to the eventual wear and tear that impairs the functionality of the moving parts within the drive. Recover information from your failed external hard drive by attempting to first recover the drive using the options in your computer's operating system. This restores the file structure of the drive, allowing you to recover data.
Plug the external drive into the system.
Click "Start" and type "cmd" in the "Search" box.
Right-click "Cmd" and click "Run as Administrator."
Type "chkdsk x: /f /r" and press "Enter," substituting "x" with the letter of the USB drive.
Press "Enter" to recover the drive's file structure. Right-click "Start," click "Explore," click the letter of the drive, and drag and drop files from the drive to extract recoverable data from the unit.
