Hard disk switch unit control to open listed price power supply, reset, and by the SATA signal communication of listed price on the hard disk SATA interface of external unit, start listed price.
Step S408, listed price performs its hard disk function, and signal is destroyed in monitoring.
After switch unit selects to start listed price, listed price becomes the hard disk of real work, can read and write normally, installs operations such as starting the operating system to it.Now close dish is in off-position.After listed price enters normal operating conditions, namely listed price controller moment monitoring destruction trigger pip can destroy instruction.
Step S410, has judged whether destruction signal.
If listed price receives destruction signal, then perform step S412, otherwise, perform step S408.
Step S412, performs data destroying function.
When receiving destruction signal and namely destroying instruction, controller can start data erase function at once, by all data erases of listed price such as Flash inside.After erasure completion, listed price is inner without any data, is in unformatted original state, can uses as new building.Process ends.
Step S414, starts close dish.
Hard disk switch unit control to open close dish power supply, reset, and the SATA signal communication of close dish is started close dish to the SATA interface of hard disk.
Step S416, judges whether by AES cryptographic check.
After selection starts close dish, user needs at Basic Input or Output System (BIOS) (Basic Input Output System, be called for short BIOS) input the password of close dish under interface, whether the password of verified users input is correct, if correct, AES deciphering could normally work, and performs step S418, otherwise performs step S416.
Step S418, close dish performs its hard disk function, and signal is destroyed in monitoring.
After switch unit selects to start close dish, close dish becomes the hard disk of real work, can read and write normally, installs operations such as starting the operating system to it.Now listed price is in off-position.After close dish enters normal operating conditions, namely close disk controller moment monitoring destruction trigger pip can destroy instruction.
Step S420, has judged whether destruction signal.
If close dish receives destruction signal, then perform step S422, otherwise, perform step S418.
Step S422, performs data destroying function.
When receiving destruction signal and namely destroying instruction, close disk controller can start data erase function at once, by all data erases of close dish such as Flash inside.After erasure completion, close dish is inner without any data, is in unformatted original state, can uses as new building.Process ends.
