External storage device 900 plug After the electronic device 200 is loaded, the electronic device 200 can automatically initialize the external storage device 900 . Then, the test unit 240 automatically executes a test program according to the script stored in the electronic device 200 . After the test program is executed, the read-write unit 250 can automatically store a test report RP to the external storage device 900 to realize the function of automatically storing the test report. The operation of each component is described in detail below through a flow chart.

Please refer to FIGS. 5A-5E , which illustrate a flowchart of a control method of the external storage device 900 for implementing the plug-and-play function and automatically storing test reports according to another embodiment.

In step S246 , the read-write unit 250 reads and writes the “mechanical hard disk” external storage device 900 at a first speed, so as to automatically store the test report RP in the external storage device 900 .

In step S256 , the read-write unit 250 reads and writes the “solid state disk” external storage device 900 at a second speed, so as to automatically store the test report RP in the external storage device 900 . The second speed is higher than the first speed.

In steps S266 and S276, the read-write unit 250 reads and writes the external storage device 900 of "other storage devices larger than 4GB" and "other storage devices not larger than 4GB" at a third speed to automatically store the test report RP to the external storage device 900 . The third speed is higher than the first speed.

Next, in steps S247 , S257 , S267 , and S277 , the read-write unit 250 determines whether the test report RP has been stored. If the test report RP has been stored, the process ends; if the test report RP has not been stored, enter steps S248 , S258 , S268 , and S278 .

In steps S248 , S258 , S268 , and S278 , the read-write unit 250 determines whether the remaining space of the external storage device 900 is sufficient. If the remaining space of the external storage device 900 is sufficient, go back to steps S246, S256, S266, S276; if the remaining space of the external storage device 900 is not enough, go to steps S249, S259, S269, S279.

In steps S249 , S259 , S269 , and S279 , the warning unit 270 sends out a warning message to notify the operator to replace the external storage device 900 .

According to the above-mentioned embodiment, the test unit 240 can automatically execute the test program on the electronic device 200 and automatically store the test report RP through the read-write unit 250 . In this way, the electronic device 200 installed with the Linux system can realize the function of automatically storing test reports.
