However, there are many tools available, including data-recovery software, that can recover most (if not all) data lost due to this problem.
1. Download one of the recovery software. Do this on a computer and hard drive without the lost or deleted data.
2. Install the program and complete the prompts in the installation process.
3. Attach the hard drive with the deleted or corrupt data to the computer where the data recovery software was installed.
4. Each of the programs listed has a wizard or step by step instructions to walk users through the recovery process.
5. Software will scan the entire hard drive, looking for deleted data and corrupted files.
6. Select the files to be recovered and direct the recovery program to the folder where the recovered files should be saved.
