When to Clean Hard Drive
On a computer, it is essential to clean a hard drive to improve performance, free up space, and protect privacy.
Here’s why cleaning a hard drive matters.
- Improve performance and stability: A full hard drive can cause system crashes, slow responsiveness, and errors when installing updates or saving files. Cleaning the disk can make the system operate more efficiently and prevent system instability.
- Free up disk space: Deleting junk files and fragmented data can free up much storage space for new apps, updates, and documents.
- Protect personal data: Before selling, donating, or recycling a computer, you should completely clean the hard drive to avoid data leaks.
