Embodiment 1
[0047] Please refer to figure 1 , Embodiment one of the present invention is: a kind of solid-state disk data erasing method, comprises the following steps:
[0048] S1. The solid-state hard disk receives a trigger signal; the trigger signal can be activated by software or by a hardware device. When activated by a hardware device, it can be activated by one-key erase button of the hardware device and send a trigger signal to the The solid-state disk connected to it; optionally, the trigger signal is a level signal, further, a low-level signal; the hardware device only needs to be able to activate and send the trigger signal;
[0049] S2. The solid state disk triggers a data erasing command including a data erasing command and a protocol shielding command according to the trigger signal; when the data erasing command is triggered, a reminder indication can be set, for example, an LED indicator is set, and when the data erasing command is triggered, LED indicator lights up;

Embodiment 2
[0055] Please refer to Figure 2-3 , the present embodiment is a solid state disk data erasing system corresponding to the above method, including a receiving module 1 , a triggering module 2 , an erasing module 3 and a prevention module 4 . The receiving module 1, the triggering module 2, the erasing module 3 and the preventing module 4 are arranged in the solid state hard disk.
[0056] The receiving module 1 is used to receive a trigger signal; optionally, the trigger signal can be triggered by the software configuration of the solid-state hard disk itself, or triggered by an erasing device connected to the interface; the erasing device is configured with The activation module 5 is configured to activate and send a trigger signal to the solid-state hard disk, the trigger signal is a level signal, further, a low level signal;
[0057] The trigger module 2 is used to trigger a data erasure command including a data erasure command and a protocol mask command according to the ...
Embodiment 3
[0062] A kind of erasing starting device, comprises SATA interface and activation module 5; Described SATA interface is used for being electrically connected with the SATA power interface of solid-state hard disk; Further, is connected with the 12V pin of solid-state hard disk SATA power interface; Described activation Module 5 is used to activate the trigger signal, so that the solid state disk triggers a data erasure command including a data erasure command and a protocol shielding command according to the trigger signal, and executes the action of erasing all data on the disk and shielding the communication protocol of the solid state hard disk physical layer. Further, an instructing module 6 is also included, which is used for instructing during the process of the solid-state hard disk erasing all data on the disk.
[0063] The solid-state hard disk does not need to be specially provided with an erasing interface, and can be connected to the erasing and starting device thro...
