How can I recover my JF910/920/930C if the writing speed is abnormally slow?

Category : Specification / Capacity / Performance

If the writing speed of your JF910/920/930C drops to about 60-100MB/s (you may check the writing speed with the speed test software), we recommend you to reformat your JF910/920/930C.

The speed shall return to normal after powered-on for a period of time.

Note: Formatting will delete all your internal files, please make sure you backup before proceeding.
