Solution 2: Revive the Hard Drive on a Different Computer

In instances where the hard drive fails to boot due to Windows OS corruption, a straightforward remedy is to extract the drive from the nonfunctional computer and link it to an alternative system. If normal access to the hard drive is established, proceed with the backup of essential data stored on the hard drive.

Solution 3: Utilize the Freezer Method

When confronted with a boot failure stemming from a hard drive issue, consider placing the hard drive in a freezer. Surprisingly, this unconventional method has proven effective in revitalizing many nonfunctional hard drives. Although not a permanent fix for a non-bootable hard drive, anecdotal evidence suggests that this approach has succeeded for some users, providing a brief window—approximately 20 minutes—to swiftly copy all the contents from the affected drive.

Solution 4: Command Prompt File Copy

If you possess Windows installation media, leverage it to boot Windows from a bootable disc or USB drive. Access the Windows Command Prompt to utilize the robust robocopy command, facilitating the seamless copying of all folders and files from the designated drive. Execute the following command: robocopy C:\tools D:\backup\tools /e

The /e modifier instructs robocopy to include all subdirectories, encompassing even empty folders. Moreover, robocopy automatically handles the copying of hidden and system files, generating new directories at the target location if they do not already exist.

Solution 5: Hard Drive Contents Viewing

In situations where direct access to the hard drive proves challenging, employ Windows Explorer to peer into its contents effortlessly.

Step 1: Convert the internal hard drive to an external one.

Step 2: Open Windows Explorer.

Step 3: View All Files.

Utilize the intuitive Windows Explorer tool to navigate through the folders on the hard drive. Please note that this method assumes the hard drive is accessible to the computer.

Tips to Prevent Hard Drive Failure

Enhance the longevity of your hard drive and minimize the risk of failure with these practical tips:

  • Moderate Usage: Avoid excessive use of your hard drive and shield it from extreme temperatures to prevent premature wear and tear.
  • Stable Power Connection: Use your system with a stable power connection.
  • Regular Health Check: Keep a close eye on the health of your hard drive. Regular proactive inspections can catch potential problems before they become worse.
  • Caution in Software Installation: Please be careful when installing software and do not obtain applications from unreliable or questionable websites.
