Abstract
The invention relates to the technical field of destruction of hard disk data of notebook computers, in particular to a method for destroying hard disk data of a notebook computer safely. According to the method, while a hardware circuit is arranged to control the destruction function, switch-on of the hardware circuit in a BIOS is controlled through software, and misoperation of hard disk data destruction is prevented through dual switch control circuits. Through the method, hard disk data of the notebook computer can be destroyed safely, and direct destruction of data caused by misoperation is prevented; because the enabled state and the forbidden state are set in the BIOS, the hard disk destroying function can be prevented from being used by mistake; when the function is not needed, the function can be forbidden in the BIOS.
Description
Technical field
The present invention relates to notebook hard disc data destroy technology field, particularly a kind of safety is carried out the method for notebook hard disc data destruction.
Background technology
Current, along with the raising to the safe and secret requirement of data, the personnel of use notebook computer need notebook computer hard disk to possess data can destroy sexual function.Can destroy hard disk has started to be applied in notebook, this kind of hard disk is generally by providing a destruction signal to use to client, this signal can be received to destruction button, but may cause maloperation when user's careless manipulation, cause hard disc data to be destroyed.
Summary of the invention
In order to solve the problem of prior art, the invention provides a kind of method that safety is carried out the destruction of notebook hard disc data, its problem that can prevent that maloperation from causing data to be destroyed occurs.
The technical solution adopted in the present invention is as follows:
Safety is carried out a method for notebook hard disc data destruction, is when hardware circuit being set control destroying function, in BIOS, the unlatching of described hardware circuit is carried out to software control, prevents the maloperation of hardware destroy by dual ON-OFF control circuit.
Hardware circuit comprises control signal output circuit and ON-OFF control circuit two parts of chipset, and the state of the control signal of chipset is arranged in BIOS, and the height of its signal respectively correspondence is destroyed enabling and forbidding of function; Described ON-OFF control circuit is the metal-oxide-semiconductor control circuit of a N raceway groove, when ON-OFF control circuit is used for not needing to destroy, by destroying the signal of switch and the destruction signal of hard disk, thoroughly disconnects.
The control signal of chipset is chosen a universal input/output signal of chipset on mainboard.
Wherein, in BIOS to the control of hardware circuit by BIOS to notebook board chip set a GPIO(universal input/output) signal carries out height and enables to realize.
Metal-oxide-semiconductor (field effect transistor) 2N7002K that ON-OFF control circuit is chosen N raceway groove realizes destroying the isolation of signal and enabling.
The beneficial effect that technical scheme provided by the invention is brought is:
Adopt the present invention, can complete the Safety destroy to notebook hard disc data, prevent that maloperation from causing data directly to be destroyed, owing to being provided with in BIOS, enabling and forbid, can avoid hard disc data to destroy function and be misapplied.When not needing this function, can in BIOS, forbid falling.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structure principle chart that a kind of safety of the present invention is carried out the method for notebook hard disc data destruction.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment mono-
As shown in Figure 1; circuit in dotted line frame is that notebook hard disk is destroyed holding circuit by mistake; this main circuit will comprise: control signal output and ON-OFF control circuit two parts of chipset; wherein the control signal of chipset can be chosen chipset(chipset on mainboard) a GPIO(universal input/output) signal; the state of GPIO signal is arranged in BIOS, and the height of its signal respectively correspondence is destroyed enabling and forbidding of function.ON-OFF control circuit is mainly the metal-oxide-semiconductor control circuit of a N raceway groove, thoroughly disconnects, to guarantee can maloperation not cause data to be destroyed when ON-OFF control circuit is used for not needing to destroy by destroying the signal of switch and the destruction signal of hard disk.。
When destruction control function being forbidden in BIOS, GPIO signal is set low, metal-oxide-semiconductor is in off state, the words that now operate destroying button, signal destroy1 is dragged down, but because metal-oxide-semiconductor has been turned off, so arrive the destruction signal destroy2 of hard disk, be still the high state of acquiescence, so can not carry out data destroying.
When destruction control function being enabled in BIOS, GPIO signal is set high, metal-oxide-semiconductor is in open mode, the words that now operate destroying button, signal destroy1 is dragged down, because metal-oxide-semiconductor has been opened, so arrive the destruction signal destroy2 of hard disk, be also set to low state, data destroying feature operation success.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (3)
1. the method that safety is carried out the destruction of notebook hard disc data, when hardware circuit being set control destroying function, in BIOS, the unlatching of described hardware circuit is carried out to software control, by dual ON-OFF control circuit, prevent the maloperation of hardware destroy.
2. the method that a kind of safety according to claim 1 is carried out the destruction of notebook hard disc data, it is characterized in that, described hardware circuit comprises control signal output circuit and ON-OFF control circuit two parts of chipset, the state of the control signal of chipset is arranged in BIOS, and the height of its signal respectively correspondence is destroyed enabling and forbidding of function; Described ON-OFF control circuit is the metal-oxide-semiconductor control circuit of a N raceway groove, when ON-OFF control circuit is used for not needing to destroy, by destroying the signal of switch and the destruction signal of hard disk, thoroughly disconnects.
3. the method that a kind of safety according to claim 2 is carried out the destruction of notebook hard disc data, is characterized in that, the control signal of described chipset is chosen a universal input/output signal of chipset on mainboard.
