the submenu of [USB # 1] or [USB # 2] and press the control
button briefly.
If you select "Self-diagnosis", you can run a self-test to see if
there are any problems like bad sectors through a full test. It can

● When the test is completed, a buzzer sounds every 3 seconds and the user is asked to check the
test results
● The user presses the button to end the test and return to menu mode
● The NCB20 will not turn off until the user presses the button, so be sure to check the test results
immediately
● Please use the full scan function with the power adapter connected
Caution
If the backup fails for any reason, a TMP folder is created. NCB20 creates a TMP folder first when
backup starts, and creates all the files in advance under the TMP folder. Then starts copying the data
and if the data copy is successful, renames the TMP folder to the actual name. Therefore, the file
may occupy only space and may contain erroneous data, thus eliminating unnecessary space wastage.
Reference
● We recommend the files in the TMP folder be deleted.
