6. Stay away from physical faults

Bad Environmental factors like dust, over hot, fire and sudden power failure/fluctuation can physically damage your hard drive. I agree that these factors can’t be forecasted in prior, but you should keep an eye to stay away from physical faults.

7. Utilize Windows power save

Windows operating system has default powers savings feature which will automatically turn off your hard drive after 20 mins of your idleness. If you often take break, you can change it to 15 mins to improve the life of your hard disk. Also, don’t use hibernate much.

If you abruptly take away the USB from PC, it will not remove the power from the drive and can cause damage to the drive as you’re suddenly unplugging it in the middle of a read/write occasion. Also check the USB is free from dust and corrosion.
