We often use external hard drive to store or backup valuable data on computer. But do you know that, in order to ensure the data safety, it's also necessary to backup your external hard drive?

Why you need to backup your external hard drive?

External hard drive faces the risk of formatting, which is one of the main reasons why you need to backup it.

1. External hard drive is portable, and because of this, it may be used on different computers. With the continually "plug in" and "pull out", it may produce errors, and you have to format the whole external disk in order to fix the drive errors.

2. Sometimes, you may want to change the usage of your external hard drive, such as making a bootable disk with it, which will format the external disk.

Formatting an external hard drive will cause all the data stored on it to be lost and difficult to recover. Thus, it's necessary to backup your external hard drive before formatting it.
