1.) Sub-point 1: Preparing for Data Loss

Before diving into the technical details, it's essential to prepare yourself and your environment. Ensure you have backups of all important data stored safely elsewhere. This proactive approach can save you a lot of headache in case of hardware failure. If backups are not an option, consider using cloud services or external hard drives that are healthy and capable of holding your valuable information.

2.) Sub-point 2: Using Command Line Tools

One of the most efficient ways to securely delete files is by using command line tools provided by operating systems like Windows and Linux. These tools overwrite the data on the disk, making recovery almost impossible.

On Windows:

1. Command Prompt: Open Command Prompt as an Administrator (Run as administrator). Use the `fsutil` command to securely erase a file or folder:

fsutil file deletemarked <filename">

Replace `<filename">` with the path to your file or directory. This command marks the file for deletion, but does not actually delete it until you restart the computer. To overwrite and permanently delete the file immediately:

fsutil file setintegritydisabled <filename">

On Linux:

1. Terminal: Use the `shred` command to securely delete files. The `-u` option will remove the file after overwriting, making recovery impossible:

shred -u /path/to/file

For directories, you can use a loop to recursively apply the shred command:

for file in $(find /path/to/directory -type f); do shred -u "file" done

3.) Sub-point 3: Using Third-Party Software

There are several third-party software tools available that can securely delete files. These tools often offer more advanced options than what the operating system provides alone.

Popular Tools:

1. Eraser: A popular tool for Windows, Eraser allows you to specify how many times it will overwrite the data before deleting it. It also supports secure deletion of directories.
2. Safe Delete: Available for both Windows and macOS, Safe Delete is a user-friendly software that overwrites deleted files multiple times and even securely wipes entire drives.
3. GParted: While primarily a disk partitioning tool, GParted can be used to securely delete data by formatting the partition or wiping it with cryptographic algorithms like LUKS.

4.) Sub-point 4: Data Destruction Best Practices

Even after deleting files from a failing hard drive, there are still some best practices to follow for added security and peace of mind:

1. Wipe the Drive: If possible, physically destroy or securely erase the entire disk using tools like Disk Utility on macOS or third-party data destruction software that uses algorithms such as Gutmann or DOD methods.
2. Dispose Properly: Do not simply discard a failing hard drive; find a responsible way to dispose of it, such as recycling it at an e-waste collection center.
3. Keep Records: Maintain records of any actions taken with respect to the data on the failed drive, including deletion and disposal methods used. This is important for legal and compliance reasons.

5.) Sub-point 5: Conclusion

In conclusion, while facing a failing hard drive can be daunting, there are several techniques available to securely delete files from it before they fall into the wrong hands or become irretrievable due to hardware failure. By preparing in advance with backups, utilizing command line tools, leveraging third-party software, and adhering to best practices for data destruction, you can protect your sensitive information effectively.

Remember, prevention is always better than cure when it comes to data security. Regularly backing up important files can save you from these kinds of situations altogether.
