detailed description

Please refer to FIG. 1 and FIG. 2 , the storage device mass production inspection system of the present invention is used to test whether there are bad blocks in several storage devices 100 , and includes a test rack 10 . In one embodiment, the storage device 100 is a fixed hard disk.

The test rack 10 includes a base plate 11 , a general power interface 13 and a plurality of connecting circuit boards 20 mounted on the base plate 11 . Each connecting circuit board 20 is used for electrically connecting a plurality of storage devices 100 . The main power interface 13 is used to connect to an output port 30 of a DC power supply. The DC power output port may be a power port installed on a computer motherboard, a mobile power output port, an output port of a power adapter, and the like. In one embodiment, the number of the connection circuit boards 20 is 4, and each connection circuit board 20 is electrically connected to 10 storage devices 100 to be tested, and the type of the total power interface 13 can be a round hole power interface or SATA power interface. The DC power supply circuit can also be an AC-to-DC circuit board installed on the base plate 11 , as long as an additional plug is plugged into the AC power, the required DC voltage can be generated.

A main power switch 21 , some sub-switches 23 , some interface slots 25 and some indicator lights 27 are installed on each connecting circuit board 20 . In one embodiment, the several interface slots 25 are arranged in parallel, the sub-switches 23 are roughly arranged on the same straight line, and the several indicator lights 27 are also roughly arranged on the same straight line.

The main power switch 21 is connected to each branch switch 23 . Each interface slot 25 is correspondingly connected to one of the sub-switches 23 and one of the indicator lights 27 therein. Each interface slot 25 is used for correspondingly inserting one of the storage devices 100 to be tested.

Please also refer to FIG. 3 , the storage device 100 includes a controller 101 and a flash 103 . A storage module 102 is set in the controller 101 . The storage module 102 stores a boot program and a test program. Mass production data is stored in the flash103. The test program is used to detect whether there is a bad block and the location of the bad block in the flash103.

The DC power supply supplies current to the corresponding storage device 100 to be tested through the main power switch 21 and the corresponding sub-switch 23, thereby starting the controller 101 for testing. The test result data will be stored in the storage module 102 . By extracting the data in the storage module 102, the bad blocks in the flash 103 can be observed according to the test results. The indicator light 27 is used to flicker during the running of the test program to show that it is currently being tested. After the test ended, the indicator light 27 went out.

In this way, only one power port is needed to detect multiple storage devices 100, and they are neatly arranged to save space.

A mass production detection method of a storage device comprises the following steps:

Step S1: Write the test program into the storage module 102 of the controller 101 . The test program is written into the controller 101 through a computer connected to a USB-to-SATA card reader. The test program is temporarily stored in the storage module 102 .

Step S2: Insert the interface of the storage device 100 to be tested into the corresponding interface slot 25 .

Step S3: The test program is run to detect whether there is a bad block in the flash 103 of the storage device 100 and record the detection result.
