Example Embodiment

[0033] Specific implementation mode 1: the following combination figure 2 To explain this embodiment, the portable electronic storage medium data erasing device of this embodiment includes a power-on button 1, a device interface, a liquid crystal display 2, a start button 3, a mode selection button 4, an up / down selection button 5, and a report Browse key 6, power input interface 7, battery 8, and data erasure control module 15,

[0034] The power-on control signal output terminal of the power button 1 is connected to the power-on control signal input terminal of the data erasure control module 15, and the display signal input terminal of the liquid crystal display 2 is connected to the display signal output terminal of the data erasure control module 15, and the start button 3 starts The control signal output terminal is connected to the start control signal input terminal of the data erasure control module 15, the mode selection control signal output terminal of the mode selec...

Example Embodiment

[0035] Specific implementation manner 2: the following combination figure 1 To explain this embodiment, the data erasing method based on the portable electronic storage medium data erasing device described in this embodiment, the specific process of the method is:

[0036] Step 1. Press the power button 1 to start work, connect the device to be erased to the device interface, and the data erasure control module 15 identifies the disk information of the device to be erased;

[0037] Step 2: Display on the LCD screen 2 that the disk of the current device interface is waiting for execution;

[0038] Step 3: The data erasure control module 15 detects whether there are HPA hidden sectors in the disk, if so, remove the HPA, if otherwise ignore the hidden sectors;

[0039] The data erasure control module 15 detects whether the disk has hidden DCO sectors, if so, remove the DCO, if otherwise ignore the hidden sectors;

[0040] Step 4. Use the mode selection key 4 and the up and down selection k...

Abstract

The invention relates to an electronic storage medium data wiping device and a data wiping method and discloses a portable electronic storage medium data wiping device and a data wiping method based on the same for solving the problems of the existing data wiping device that fewer functions are provided, the destroying speed is low, the portable degree is low and the wiping result is uncertain. The data wiping device provided by the invention comprises a power-on key, an equipment interface, a liquid crystal display, a starting key, a mode select key, an up/down selection key, a reporting browse key, a power input interface, a battery and a data wiping control module. The data wiping method comprises the following specific processes of: recognizing information of an equipment disk; displaying that the interfaces are in a stage of waiting for execution; detecting whether the disk has an HPA(high-power amplifier) hiding fan-shaped region and a DCO (data control office) hiding fan-shaped region; if so, removing the HPA and the DCO; if not, neglecting the fan-shaped regions; and selecting a wiping mode: rapid wiping or user-defined wiping; formatting the disk, and generating an wiping recording report. The data wiping device and the data wiping method provided by the invention are used for wiping data of different media.

Description

technical field [0001] The invention relates to an electronic storage medium data erasing device and a data erasing method based on the device. Background technique [0002] Every year in our country, millions of hard disks need to be phased out due to damage, obsolete and other reasons, and more U disks need to be destroyed. Such a large scale of destruction will inevitably cause unimaginable damage if effective management and technical means cannot be used. Consequences of disclosure. [0003] The data destruction technology born in the early 21st century is a symbol of the formation of a complete system in the field of confidential data information security. If "data recovery technology" is compared to the "spear" in the field of confidential data information security, then "data destruction technology" is a The "shield" in the field of confidential data information security, and the role of the "shield" is stronger than the "spear". [0004] The common data destruction...
