Safe Mode and Disk Check

  1. Step 1: Restart your computer and enter Safe Mode by pressing F8 during boot-up and selecting 'Safe Mode'. This will load a minimal set of drivers and prevent any potentially conflicting system files from loading.
  2. Step 2: Once in Safe Mode, open the Command Prompt as an administrator. Type the command `chkdsk C:` (where C: is the drive letter of your external hard disk) and press Enter. If the check disc process completes without errors, it may indicate that the issue lies elsewhere.
  3. Step 3: If the check disc process indicates corruption or errors, proceed to the next step.

Disk Error Checking and Repair

  1. Step 1: Open the Disk Management tool by pressing Win + R, typing `diskmgmt.msc` in the Run dialog box, and pressing Enter. Locate your external hard disk in the list of drives.
  2. Step 2: Right-click on the corrupted drive and select 'Properties'. In the Properties window, click on the 'Error Checking' tab. If an error is detected, click 'Start' to begin the repair process.
  3. Step 3: If the repair process completes successfully, you should be able to access your external hard disk again.

💡 Conclusion

To resolve the 'The file or directory is corrupted and unreadable' error on your ADATA 500GB external hard disk, try the Safe Mode and Disk Check method first. If this fails, proceed with the Disk Error Checking and Repair method. If you're still unable to access your external hard disk after trying these methods, it may be necessary to seek professional assistance or consider replacing the drive.
