Referring to FIG. 1, a preferred embodiment of the hard disk 1 with time indication function of the present invention includes a master wafer 10, a memory chip 11, a single chip microcomputer 12, a digital tube 13 and resistors R1-R12. The other electronic components on the hard disk 1 are the same as those of the conventional hard disk, and will not be described herein.

The master wafer 10 is connected to the memory wafer 11 for controlling the memory wafer 11 for reading and writing data. The input/output pin GPIO1 of the master wafer 10 is connected to the input pin RC0 of the microcontroller 12 via the resistor R1. The input/output pin GPIO2 of the master wafer 10 is connected to the input pin RC1 of the microcontroller 12 via the resistor R2. The input/output pin GPIO3 of the master wafer 10 is connected to the input pin RC2 of the microcontroller 12 via the resistor R3. The voltage pin RE3 of the single chip microcomputer 12 is connected to a voltage source P5V_R and connected to a voltage source P5V via the resistor R4. The voltage pin VDD of the microcontroller 12 is connected to the voltage source P5V. The ground pins VSS1 and VSS2 of the microcontroller 12 are both grounded. The output pins RA0-RA7 of the single chip microcomputer 12 are connected to the pins 10, 9, 8, 5, 4, 2, 3 and 7 of the digital tube 13 via the resistors R5-R12, respectively. Pins 1 and 2 of the digital tube 13 are connected to the voltage source P5V.

When the hard disk 1 is powered on, the master wafer 10 first reads the power-on time stored in its internal memory, such as 0 days (ie, the hard disk 1 has not been used before), and uses the stored The power time, such as 0 days, is based on the power-on time of the hard disk 1, such as 5 days, and the 5 days after the recording is stored in the internal memory, when the hard disk 1 is powered on again, The master wafer 10 reads the power-on time stored in its internal memory, such as 5 days (that is, the usage time used before the hard disk 1 is 5 days), and the stored power-on time, such as 5 days. Basically, the power-on time of the hard disk 1 is recorded, such as 8 days, and the 13 days after the recording is stored in the internal memory, and so on, thereby obtaining the usage time of the hard disk 1. In order to facilitate display, the use time of the hard disk 1 is displayed for a period of one year. When the power-on time of the hard disk 1 is less than 1 year, the master wafer 10 determines that the hard disk 1 is used for 0 years, and when the power-on time of the hard disk 1 is greater than 1 year and less than 2 years, The master wafer 10 determines that the hard disk 1 is used for one year.
