TL;DR: In this paper, a write protect system includes a controller coupled to at least one memory storage device via information transfer busses and a control data bus for monitoring signals transmitted thereover.
Abstract: A write protect system prevents inadvertent attempts to write data into a permanent memory storage device (such as a disc drive) containing valuable data that might be destroyed by such a write attempt. The write protect system includes a controller coupled to at least one memory storage device via information transfer busses and a control data bus. The controller sends signals for writing data into selected ones of memory devices. A circuit is coupled into the control data bus for monitoring signals transmitted thereover. Responsive to the monitoring circuit, access is barred to preclude writing into a specific one of the memory devices whereby data may not be accidentally written into the specific memory. The barring is cancelled if a specific action is taken whereby data may be deliberately written into a specific memory.

TL;DR: In this article, a computer hard disc data detecting equipment and a data detecting method are presented. But the detection equipment and the method are suitable for data detection of each brand of hard disc, and are convenient to operate, low in technical requirement and high in automation degree.
Abstract: The invention discloses computer hard disc data detecting equipment and a computer hard disc data detecting method. The detecting equipment comprises a main board and an external interface, wherein a CPU (central processing unit) used for controlling the whole data detection work is arranged on the main board; the external interface is connected with the main board and comprises a USB (universal serial bus) interface, an IDE (integrated development environment) interface, an ATA (advanced technology attachment) interface, an SCSI (Small Computer System Interface) interface, an HD (hard disc) interface and a COM (Component Object Model) interface; the main board is also connected with a key module and a display module. The method comprises the following steps of hard disc appearance check, electrification detection, parameter detection, monitor detection, hard disc lock detection, disc detection and data detection. The detecting equipment and the detecting method are suitable for data detection of each brand of hard disc, and are convenient to operate, low in technical requirement and high in automation degree.

TL;DR: In this paper, a computer software and data maintaining, supporting and restoring system, where dynamic data file is identified and redirected or copied to hidden partition in the computer hard disc, any dynamic file change is automatically backuped to the hidden partition.
Abstract: The invention discloses a computer software and data maintaining, supporting and restoring system, where dynamic data file is identified and redirected or copied to hidden partition in the computer hard disc. Any dynamic data file change is automatically backuped to the hidden partition. The dynamic data file in the hidden partition includes computer operating environment, therefore it can restore the computer environment according to the dynamic data file, and the dynamic data file in the hidden partition includes the data to be ended until the computer system failure happens.

TL;DR: In this paper, the authors proposed a utility model for computer hard disk anti-theft monitoring and anti-leakage self-destruction systems, which overcomes the problem that in the prior art computer hard disc can not be prevented from being thieved and the thieved data can not prevent from being leaked.
Abstract: The utility model relates to a technical field of computer data safety assurance, in particular to a computer hard disk anti-theft monitoring and anti-leakage self-destruction system, which overcomes the problem that in the prior art computer hard disc can not be prevented from being thieved and the thieved data can not be prevented from being leaked. The utility model provides technical proposal that: a computer hard disk anti-theft monitoring and anti-leakage self-destruction system is composed of an external control center and a terminal execution mechanism, the external control center is composed of an external GPS module, an external wireless transceiver module, an external power source module, and an external alarming device that are around an external controller; the terminal execution mechanism comprises a terminal power source module, a terminal alarming device, a terminal self-destruction device, a terminal GPS positioning module and a terminal transceiver module that are around a terminal controller, wherein the terminal GPS positioning module and the terminal wireless transceiver module are corresponding to the external control center. The utility model has the advantages of automatic alarming, double protection and high safety performance.
