What Is a Power Surge?
A power surge is talking about a sudden electric current spike of your home or office. Like the common instant power loss issue, it happens without any sign, doesn’t last long, but, still arouse damages to your appliances of your home or office. Moreover, if you are coincidentally using your digital storage devices, including some computer hard disks, external hard drives, USB flash drives, SD card or other memory cards, on your computer, the power surges also can corrupt your storage devices and bring your hard drive or memory card data loss troubles.
There are often two types of power surges: the internal power surges and external power surges.
The internal power surge, as the most commonly encountered type for people, often happen due to the high-power electrical devices, like elevators, air conditioners and refrigerators, etc, which can bring people an electric current spike when they are switched on or their motors are turned off. Why? When they are turned on or their compressors/motors are shut down, they will require a sudden and instant power to support the changing, which will also affect the stability of the voltage. That’s why the internal power surge occurs.
And the external power surge often happens for some natural reasons, like the lighting and thunders. That’s also why people are suggested to turn down all appliances before raining in the summer.
Generally, though the internal power surges harms your appliances far less than the external power surges due to lightings or thunders, they also are able to damage or even corrupt your digital storage devices, like some commonly used USB hard disks, flash drives and memory cards, when they are still in use on your computer.

Moreover, what’s worse, if you do coincidentally prepare no memory card or hard drive data backups elsewhere, it even can bring you more troublesome data loss problems.
Please Note: No matter what types of storage device data loss problems you’ve encountered, including not formatted drive or memory card data loss troubles, RAW format drive or memory card data loss troubles and more, recover hard drive or memory card with data recovery software before any format to avoid permanent data loss.
