What should I look for when defragmenting a hard drive?

1. Ensure that you have a valid backup of all your important data stored on the hard drive.

2. Defragment the hard drive regularly; it is recommended to use a defragmenter tool that is specifically designed for the operating system you are using.
3. Use the “Check Disk” feature of your operating system to check for errors and bad sectors on the hard drive.
4. After the defragmentation process, you should also check the hard drive again with “Check Disk” to ensure that no errors were created during the defrag process.
5. Finally, run a thorough scan of the hard drive for any malicious software or viruses that could be causing damage.
