What Free Tools Cannot Do?
You might be surprised to know that even the best free hard drive health check software only identifies problems and it cannot repair any faulty drive nor can it recover deleted or lost files. Furthermore a “Good” result does not guarantee you that everything is perfectly safe as controller or electronic failures can occur any time. Therefore I always advise everyone to keep a backup of all their important data.
What to Do If Your Hard Drive Health Is Bad
- Back up first: You must copy all your important files to another drive or cloud storage.
- Stop heavy scans: Quickly stop scanning your drive again and again as long surface tests will put extra stress on your weak drive.
- Check cables and ports: Check for bad SATA or USB cable.
- Save the report: You should keep a screenshot of the SMART data for warranty or support.
- Replace your drive if errors keep rising.
Recover Data from a Failing Hard Drive
Warning signs from the hard drive sometimes come too late and as a result your important files go missing, in this case your drive shows as RAW or it asks you to format it. Well it is important to know that deleted files generally stay on your disk until you write any new data so you must stop using the drive right away.
This is where recovery software helps you rightly.
