Embodiment 1

[0028] Such as figure 1 As shown, the present embodiment provides a SATA hard disk write protection method, including:

[0029] Step 101, receiving a hard disk operation instruction sent by a pre-connected user terminal.

[0030] In this embodiment, it may be directly connected to the user terminal, or may be connected to the user terminal through a USB-SATA interface converter, which will not be repeated here. The hard disk operation instruction received in step 101 may be an access instruction, a write operation instruction, or other instructions, which are not limited here.

[0031] Step 102, judging whether the hard disk operation command belongs to a write operation command according to a preset write operation standard.

[0032] In this embodiment, the manner of judging whether the hard disk operation instruction belongs to the write operation instruction through step 102 may be to match the hard disk operation instruction with the write operation standard one by one. ...

Embodiment 2

[0042] Such as image 3 Shown, this embodiment provides a kind of SATA hard disk write protection method, and this method and figure 2 Similar, the difference is that it also includes:

[0043] Step 105, judging whether to enable hard disk write protection.

[0044] In this embodiment, after receiving the hard disk operation instruction through step 101, it may first be judged through step 105 whether to enable the hard disk write protection; and when it is confirmed to be enabled, execute step 102;

[0045] In this embodiment, if the hard disk write protection is enabled, step 102 and step 103 are used to filter the hard disk operation instructions belonging to the write operation instruction; otherwise, the hard disk operation instruction is directly sent through step 104, which will not be repeated here.

[0046]The present invention has the following beneficial effects: after the user terminal sends out the hard disk operation command, it is judged whether the hard disk...

Embodiment 3

[0048] Such as Figure 4 As shown, the embodiment of the present invention provides a kind of SATA hard disk write protection system, comprising:

[0049] At least one SATA hard disk 401, write protection device 402 and user terminal 403; The write protection device includes: at least one first SATA connector 4021, FPGA chip 4022 and second SATA connector 4023; said at least one first SATA connector and said The second SATA connector is connected with the FPGA chip respectively; each SATA hard disk is connected with a first SATA connector, and the number of the SATA hard disk is corresponding to the number of the first SATA connector; the second SATA connector is connected with the first SATA connector. The user terminal is connected; the FPGA chip is used to receive the hard disk operation instruction sent by the user terminal; judge whether the hard disk operation instruction belongs to a write operation instruction according to the preset write operation standard; if so, fi...

Abstract

The invention discloses an SATA (serial advanced technology attachment) hard disc write-protection method and system and relates to the computer technology and aims to solve the problem of the prior art that the software write-protection only functions to the non-guide area of the hard disc, and the guide area of the hard disc fails to perform the software write protection. The technical scheme includes S10, receiving a hard disc operation command sent from a subscriber terminal pre-connected; S20, according to the preset write operation standard, judging whether or the hard disc operation command belongs to write operation commands, if yes, executing the S30; S30, filtering the hard disc operation command and executing the S10 again.

Description

technical field [0001] The invention relates to computer technology, in particular to a SATA hard disk write protection method and system. Background technique [0002] At present, hard disks are widely used as large-capacity information storage devices in various archives, cultural centers, libraries, art galleries, exhibition halls, and industry data centers. In order to improve the security of information, banks, digital libraries, and public security evidence agencies all require that the stored data cannot be modified, that is, it has write protection. [0003] In the prior art, the hard disk is usually write-protected by software; however, the software write protection is only for the non-boot partition of the hard disk, and the boot partition of the hard disk cannot be software write-protected. Contents of the invention [0004] The invention provides a SATA hard disk write protection method and system, which can carry out write protection on the entire hard disk. ...
