[0052] With reference to the block diagram of the first embodiment of the system of the present invention shown in Figure 1:

[0053]The system is used to control the connection of the hard disk signal line according to the instruction of the CPU after the hard disk is inserted, and provides the protection function for the hot insertion of the hard disk.

[0054] It includes a detection circuit 111 and a switch circuit 112 . The detection circuit 111 is used to generate an insertion signal, which is output to an I / O pin 5 of the CPU 14 of the core processing board, so that the CPU can detect whether the hard disk is fully inserted according to the signal. The switch circuit 112 is arranged on the interface circuit board 10 of the hard disk, and its control terminal 1 is connected to another I / O pin 6 of the CPU, and the other control terminal 2 is connected to the power supply or "ground". The controlled terminals 3 and 4 are respectively connected to the signal lines of the ...

Abstract

The invention discloses a hardware hot drawing preserving system, which comprises; inserting the signal control apparatus on the interface circuit plate of the hardware, wherein the interface circuit is connected with the CPU of the core processing plate, which can control the connection of the hard disk signal wire according to the CPU order; pulling out the signal inductor on the interface circuit plate of the hardware, wherein the interface circuit is connected with the CPU of the core processing plate, which can induct weather the hardware can be safely pulled out according to the CPU order.

Description

technical field [0001] The invention relates to a hard disk hot-swapping safety technology, in particular to a hard disk hot-swapping protection system and method. Background technique [0002] In the composition structure of the computer, there is a very important part, which is the memory. The memory is a component used to store programs and data. For a computer, only with memory can it have a memory function and ensure normal operation. With the rapid development of computers, storage devices are also becoming more and more advanced, and their storage capacity is also increasing. A hard disk is an external memory that uses magnetism to record information. It has the advantages of large storage capacity and high data transmission rate. [0003] As a storage device, the hard disk has data signals as well as power signals on its interface. When a hard disk without a protection circuit design is hot-swapped, it is likely to have negative effects in the above two places, th...
